The platform eliminates microservices complexity in favor of a monolithic architecture that can be functional within 1-2 weeks while supporting approximately 10 concurrent bots. The system focuses on core functionality including data collection, strategy execution, backtesting, and visualization without requiring advanced monitoring or orchestration tools. + +## System Architecture Overview + +The platform follows a streamlined monolithic design that consolidates all components within a single application boundary. This approach enables rapid development while maintaining clear separation between functional modules for future scalability.The architecture consists of six core components working together: Data Collection Module for exchange connectivity, Strategy Engine for unified signal generation, Bot Manager for concurrent bot orchestration, PostgreSQL database for data persistence, Backtesting Engine for historical simulation, and Dashboard for visualization and control. + +## Simplified Technical Stack + +### Core Technologies + +The platform utilizes a Python-based technology stack optimized for rapid development. The backend employs Python 3.10+ with FastAPI or Flask for API services, PostgreSQL 14+ with TimescaleDB extension for time-series optimization, and Redis for real-time pub/sub messaging. The frontend leverages Dash with Plotly for interactive visualization and bot control interfaces. + +### Database Design + +The database schema emphasizes simplicity while supporting essential trading operations. Core tables include raw_market_data for exchange data storage, candles for OHLCV aggregation, strategies for algorithm definitions, bots for instance management, signals for trading decisions, trades for execution records, and bot_portfolio for performance tracking. + +## Development Methodology + +### Two-Week Implementation Timeline + +The development follows a structured three-phase approach designed for rapid deployment. Phase 1 (Days 1-5) establishes foundational components including database setup, data collection implementation, and basic visualization. Phase 2 (Days 6-10) completes core functionality with backtesting engine development, trading logic implementation, and dashboard enhancement. Phase 3 (Days 11-14) focuses on system refinement, comprehensive testing, and deployment preparation. + +### Strategy Implementation Example + +The platform supports multiple trading strategies through a unified interface design. A simple moving average crossover strategy demonstrates the system's capability to generate buy and sell signals based on technical indicators.This example strategy shows how the system processes market data, calculates moving averages, generates trading signals, and tracks portfolio performance over time. The visualization includes price movements, moving average lines, signal markers, and portfolio value progression. + +## Backtesting and Performance Analysis + +### Strategy Validation Framework + +The backtesting engine enables comprehensive strategy testing using historical market data. The system calculates key performance metrics including total returns, Sharpe ratios, maximum drawdown, and win/loss ratios to evaluate strategy effectiveness. + +### Portfolio Management + +The platform tracks portfolio allocation and performance throughout strategy execution. Real-time monitoring capabilities show the distribution between cryptocurrency holdings and cash reserves. + +## Simplified Data Flow + +### Real-Time Processing + +The data collection module connects to exchange APIs to retrieve market information including order books, trades, and candlestick data. Raw data is stored in PostgreSQL while processed information is published through Redis channels for real-time distribution to active trading bots. + +### Signal Generation and Execution + +Strategies subscribe to relevant data streams and generate trading signals based on configured algorithms. The bot manager validates signals against portfolio constraints and executes simulated or live trades according to bot configurations. + +## Future Scalability Considerations + +### Microservices Migration Path + +While implementing a monolithic architecture for rapid deployment, the system design maintains clear component boundaries that facilitate future extraction into microservices. API-first design principles ensure internal components communicate through well-defined interfaces that can be externalized as needed. + +### Authentication and Multi-User Support + +The current single-user design can be extended to support multiple users through role-based access control implementation. Database schema accommodates user management tables and permission structures without requiring significant architectural changes. + +### Advanced Monitoring Integration + +The simplified monitoring approach can be enhanced with Prometheus and Grafana integration when scaling requirements justify the additional complexity. Current basic monitoring provides foundation metrics that can be extended to comprehensive observability systems. + +## Technical Implementation Details + +### Time Series Data Management + +The platform implements proper time aggregation aligned with exchange standards to ensure accurate candle formation. Timestamp alignment follows right-aligned methodology where 5-minute candles from 09:00:00-09:05:00 receive the 09:05:00 timestamp. + +### Performance Optimization + +Database indexing on timestamp and symbol fields ensures efficient time-series queries. Connection pooling prevents database connection leaks while prepared statements optimize query execution. Memory management includes proper cleanup of data objects after processing to maintain system stability. + +## Success Metrics and Validation + +### Development Milestones + +Platform success is measured through specific deliverables including core functionality completion within 14 days, system stability maintenance at 99% uptime during internal testing, successful backtesting of at least 3 different strategies, and concurrent operation of 2+ bots for 72+ hours. + +### Strategy Testing Capabilities + +The system enables comprehensive strategy validation through historical simulation, real-time testing with virtual portfolios, and performance comparison across multiple algorithms. Backtesting results provide insights into strategy effectiveness before live deployment. + +## Conclusion + +This simplified crypto trading bot platform balances rapid development requirements with future scalability needs. The monolithic architecture enables deployment within 1-2 weeks while maintaining architectural flexibility for future enhancements. Clear component separation, comprehensive database design, and strategic technology choices create a foundation that supports both immediate testing objectives and long-term platform evolution. + +The platform's focus on essential functionality without unnecessary complexity ensures teams can begin strategy testing quickly while building toward more sophisticated implementations as requirements expand. This approach maximizes development velocity while preserving options for future architectural evolution and feature enhancement. diff --git a/tasks/prd-crypto-bot-dashboard.md b/tasks/prd-crypto-bot-dashboard.md deleted file mode 100644 index 6408a49..0000000 --- a/tasks/prd-crypto-bot-dashboard.md +++ /dev/null @@ -1,159 +0,0 @@ -# Product Requirements Document: Crypto Trading Bot Dashboard - -## Introduction/Overview - -Create a simple control dashboard for managing and monitoring multiple cryptocurrency trading bots simultaneously.

2025 17:45:57 +0800 Subject: [PATCH 05/73] Update database schema and configuration for Crypto Trading Bot Platform - Added new SQLAlchemy models in `database/models.py` for market data, trades, bots, signals, and performance tracking. - Updated `docker-compose.yml` to use TimescaleDB for PostgreSQL and configured shared preload libraries. - Created new schema files: `schema.sql` for the complete database setup and `schema_clean.sql` for a simplified version without hypertables. - Updated documentation in `setup.md` to reflect changes in database initialization and service setup. ---

Updated `docker-compose.yml` to remove hardcoded passwords, relying on environment variables for PostgreSQL and Redis configurations. - Modified `env.template` to reflect new password settings and ensure secure handling of sensitive information. - Introduced a new `database/connection.py` file for improved database connection management, including connection pooling and session handling. - Updated `database/models.py` to align with the new schema in `schema_clean.sql`, utilizing JSONB for optimized data storage. - Enhanced `setup.md` documentation to clarify the initialization process and emphasize the importance of the `.env` file for configuration. - Added a new `scripts/init_database.py` script for automated database initialization and verification, ensuring all tables are created as expected. --- config/settings.py | 4 +- database/connection.py | 487 ++++++++++++++++++ database/init/init.sql | 18 +- .../init/{schema.sql => schema_clean.sql} | 63 +-- database/models.py | 19 +- database/schema_clean.sql | 20 + docker-compose.yml | 6 +- docs/setup.md | 80 ++- env.template | 8 +- scripts/dev.py | 4 +- scripts/init_database.py | 179 +++++++ tasks/tasks-crypto-bot-prd.md | 35 +- 12 files changed, 781 insertions(+), 142 deletions(-) create mode 100644 database/connection.py rename database/init/{schema.sql => schema_clean.sql} (82%) create mode 100644 scripts/init_database.py diff --git a/config/settings.py b/config/settings.py index 7e64d59..daecdd9 100644 --- a/config/settings.py +++ b/config/settings.py @@ -21,10 +21,10 @@ class DatabaseSettings(BaseSettings): """Database configuration settings.""" host: str = Field(default="localhost", env="POSTGRES_HOST") -

+Set the log level when getting a logger: +```python +# Available levels: DEBUG, INFO, WARNING, ERROR, CRITICAL +logger = get_logger('component_name', 'DEBUG') # Show all messages +logger = get_logger('component_name', 'ERROR') # Show only errors and critical +``` + +### Verbose Console Logging + +Control console output with the `verbose` parameter: + +```python +# Explicit verbose

(default behavior) +logger = get_logger('bot_manager', verbose=None) # Uses VERBOSE_LOGGING from .env +``` + +Environment variables for console logging: +```bash +# In .env file or environment +VERBOSE_LOGGING=true # Enable verbose console logging +LOG_TO_CONSOLE=true # Alternative environment variable (backward compatibility) +``` + +Console output respects log levels: +- **DEBUG level**: Shows all messages (DEBUG, INFO, WARNING, ERROR, CRITICAL) +- **INFO level**: Shows INFO and above (INFO, WARNING, ERROR, CRITICAL) +- **WARNING level**: Shows WARNING and above (WARNING, ERROR, CRITICAL) +- **ERROR level**: Shows ERROR and above (ERROR, CRITICAL) +- **CRITICAL level**: Shows only CRITICAL messages + +### Automatic Log Cleanup + +Control automatic cleanup of old log files: +

clean_old_logs=False) + +# Custom retention (keep 14 most recent log files) +logger = get_logger('bot_manager', max_log_files=14) +``` + +**How automatic cleanup works:** +- Triggered every time a new log file is created (date change) +- Keeps only the most recent `max_log_files` files +- Deletes older files automatically +- Based on file modification time, not filename + +## Advanced Features + +### Manual Log Cleanup + +Remove old log files manually based on age: +```python +from utils.logger import cleanup_old_logs + +# Remove logs older than 30 days for a specific component +cleanup_old_logs('bot_manager', days_to_keep=30) + +# Or clean up logs for multiple components +for component in ['bot_manager', 'data_collector', 'strategies']: + cleanup_old_logs(component, days_to_keep=7) +``` + +### Error Handling with Context + +```python +try: + risky_operation() +except Exception as e: + logger.error(f"Operation failed: {e}", exc_info=True) + # exc_info=True includes the full stack trace +``` + +### Structured Logging + +For complex data, use structured messages: +```python +# Good: Structured information +logger.info(f"Trade executed: symbol={symbol}, price={price}, quantity={quantity}") + +# Even better: JSON-like structure for parsing +logger.info(f"Trade executed", extra={ + 'symbol': symbol, + 'price': price, + 'quantity': quantity, + 'timestamp': datetime.now().isoformat() +}) +``` + +## Configuration Examples + +### Development Environment +```python +# Verbose logging with frequent cleanup +logger = get_logger( + 'bot_manager', + log_level='DEBUG', + verbose=True, + max_log_files=3 # Keep only 3 days of logs +) +``` + +### Production Environment +```python +# Minimal console output with longer retention +logger = get_logger( + 'bot_manager', + log_level='INFO', + verbose=False, + max_log_files=30 # Keep 30 days of logs +) +``` + +### Testing Environment +```python +# Disable cleanup for testing +logger = get_logger( + 'test_component', + log_level='DEBUG', + verbose=True, + clean_old_logs=False # Don't delete logs during tests +) +``` + +## Environment Variables + +Create a `.env` file to control default logging behavior: + +```bash +# Enable verbose console logging globally +VERBOSE_LOGGING=true + +# Alternative (backward compatibility) +LOG_TO_CONSOLE=true +``` + +## Best Practices + +### 1. Component Naming + +Use descriptive, consistent component names: +- `bot_manager` - for bot lifecycle management +- `data_collector` - for market data collection +- `strategies` - for trading strategies +- `backtesting` - for backtesting engine +- `dashboard` - for web dashboard + +### 2. Log Level Guidelines + +- **DEBUG**: Detailed diagnostic information, typically only of interest when diagnosing problems +- **INFO**: General information about program execution +- **WARNING**: Something unexpected happened, but the program is still working +- **ERROR**: A serious problem occurred, the program couldn't perform a function +- **CRITICAL**: A serious error occurred, the program may not be able to continue + +### 3. Verbose Logging Guidelines + +```python +# Development: Use verbose logging with DEBUG level +dev_logger = get_logger('component', 'DEBUG', verbose=True, max_log_files=3) + +# Production: Use INFO level with no console output +prod_logger = get_logger('component', 'INFO', verbose=False, max_log_files=30) + +# Testing: Disable cleanup to preserve test logs +test_logger = get_logger('test_component', 'DEBUG', verbose=True, clean_old_logs=False) +``` + +### 4. Log Retention Guidelines + +```python +# High-frequency components (data collectors): shorter retention +data_logger = get_logger('data_collector', max_log_files=7) + +# Important components (bot managers): longer retention +bot_logger = get_logger('bot_manager', max_log_files=30) + +# Development: very short retention +dev_logger = get_logger('dev_component', max_log_files=3) +``` + +### 5.

+0800 Subject: [PATCH 10/73] Implement enhanced data collection system with health monitoring and management - Introduced `BaseDataCollector` and `CollectorManager` classes for standardized data collection and centralized management. - Added health monitoring features, including auto-restart capabilities and detailed status reporting for collectors. - Updated `env.template` to include new logging and health check configurations. - Enhanced documentation in `docs/data_collectors.md` to provide comprehensive guidance on the new data collection system. - Added unit tests for `BaseDataCollector` and `CollectorManager` to ensure reliability and functionality. --- data/__init__.py | 25 + data/base_collector.py | 667 +++++++++++++++ data/collector_manager.py | 529

00:00:00 2001 From: "Vasily.onl" Date: Sat, 31 May 2025 20:49:31 +0800 Subject: [PATCH 11/73] Add OKX data collector implementation and modular exchange architecture - Introduced the `OKXCollector` and `OKXWebSocketClient` classes for real-time market data collection from the OKX exchange. - Implemented a factory pattern for creating exchange-specific collectors, enhancing modularity and scalability. - Added configuration support for the OKX collector in `config/okx_config.json`. - Updated documentation to reflect the new modular architecture and provide guidance on using the OKX collector. - Created unit tests for the OKX collector and exchange factory to ensure functionality and reliability. - Enhanced logging and error handling throughout the new implementation for improved monitoring and debugging. --- config/okx_config.json | 65 +++ data/exchanges/__init__.py | 39 ++ data/exchanges/factory.py | 196 +++++++ data/exchanges/okx/__init__.py | 14 +

common data processing framework for OKX exchange - Introduced a modular architecture for data processing, including common utilities for validation, transformation, and aggregation. - Implemented `StandardizedTrade`, `OHLCVCandle`, and `TimeframeBucket` classes for unified data handling across exchanges. - Developed `OKXDataProcessor` for OKX-specific data validation and processing, leveraging the new common framework. - Enhanced `OKXCollector` to utilize the common data processing utilities, improving modularity and maintainability. - Updated documentation to reflect the new architecture and provide guidance on the data processing framework. - Created comprehensive tests for the new data processing components to ensure reliability and functionality. --- data/common/__init__.py | 52 ++

00:00:00 2001 From: "Vasily.onl" Date: Sat, 31 May 2025 22:30:56 +0800 Subject: [PATCH 14/73] Add clean monitoring and production data collection scripts - Introduced `monitor_clean.py` for monitoring database status with detailed logging and status updates. - Added `production_clean.py` for running OKX data collection with minimal console output and comprehensive logging. - Implemented command-line argument parsing for both scripts to customize monitoring intervals and collection durations. - Enhanced logging capabilities to provide clear insights into data collection and monitoring processes. - Updated documentation to include usage examples and descriptions for the new scripts, ensuring clarity for users. --- scripts/monitor_clean.py | 226 +++++++++++++++++++++++++

From bc13cfcbe0c7db5941f41dbd3f98289aedd59993 Mon Sep 17 00:00:00 2001 From: "Vasily.onl" Date: Sun, 1 Jun 2025 14:42:29 +0800 Subject: [PATCH 15/73] Enhance logging capabilities across data collection components - Added optional logger parameter to various classes including `BaseDataCollector`, `CollectorManager`, `RealTimeCandleProcessor`, and `BatchCandleProcessor` to support conditional logging. - Implemented error-only logging mode, allowing components to log only error and critical messages when specified. - Updated logging calls to utilize new helper methods for improved readability and maintainability. - Enhanced documentation to include details on the new logging system and its usage across components. - Ensured that child components inherit the logger from their parent components for consistent logging behavior. --- data/base_collector.py | 332 ++++++++++++++++----------- data/collector_manager.py | 108 ++++++--- data/common/aggregation.py | 38 +--

type + } +} +``` + +## Integration with TCP Platform + +### Aggregation Strategy Compatibility + +The indicators module is designed to work seamlessly with the TCP platform's aggregation strategy: + +- **Right-Aligned Timestamps**: Uses `end_time` from OHLCV candles +- **Sparse Data Support**: Handles missing candles without interpolation +- **No Future Leakage**: Only processes completed candles +- **Time Boundary Respect**: Maintains proper temporal ordering + +### Real-Time Processing + +```python +from data.common.aggregation import RealTimeCandleProcessor +from data.common.indicators import TechnicalIndicators + +# Set up real-time processing +candle_processor = RealTimeCandleProcessor(symbol='BTC-USDT', exchange='okx') +indicators = TechnicalIndicators() + +# Process incoming trades and calculate indicators +def on_new_candle(candle): + # Get recent candles for indicator calculation + recent_candles = get_recent_candles(symbol='BTC-USDT', count=50) + + # Calculate indicators + sma_results = indicators.sma(recent_candles, period=20) + rsi_results = indicators.rsi(recent_candles, period=14) + + # Use indicator values for trading decisions + if sma_results and rsi_results: + latest_sma = sma_results[-1].values['sma'] + latest_rsi = rsi_results[-1].values['rsi'] + + # Trading logic here... +``` + +### Database Integration + +```python +from database.models import IndicatorData + +# Store indicator results in database +def store_indicators(indicator_results, indicator_type): + for result in indicator_results: + indicator_data = IndicatorData( + symbol=result.symbol, + timeframe=result.timeframe, + timestamp=result.timestamp, + indicator_type=indicator_type, + values=result.values, + metadata=result.metadata + ) + session.add(indicator_data) + session.commit() +``` + +## Performance Considerations + +### Memory Usage +- Process indicators in batches for large datasets +- Use appropriate period lengths to balance accuracy and performance +- Consider data retention policies for historical indicator values + +### Calculation Frequency +- Calculate indicators only when new complete candles are available +- Cache recent indicator values to avoid recalculation +- Use incremental updates for real-time scenarios + +### Optimization Tips +- Use `calculate_multiple_indicators()` for efficiency when computing multiple indicators +- Limit the number of historical candles to what's actually needed +- Consider using different timeframes for different indicators + +## Error Handling + +The module includes comprehensive error handling: + +- **Insufficient Data**: Returns empty results when not enough data is available +- **Invalid Configuration**: Validates configuration parameters before calculation +- **Data Quality Issues**: Handles NaN values and missing data gracefully +- **Type Errors**: Converts data types safely with fallback values + +## Testing + +The module includes comprehensive unit tests covering: + +- All indicator calculations with known expected values +- Sparse data handling scenarios +- Edge cases (insufficient data, invalid parameters) +- Configuration validation +- Multiple indicator batch processing + +Run tests with: +```bash +uv run pytest tests/test_indicators.py -v +``` + +## Future Enhancements + +Potential future additions to the indicators module: + +- **Additional Indicators**: Stochastic, Williams %R, Commodity Channel Index +- **Custom Indicators**: Framework for user-defined indicators +- **Performance Metrics**: Calculation timing and memory usage statistics +- **Streaming Updates**: Incremental indicator updates for real-time scenarios +- **Parallel Processing**: Multi-threaded calculation for large datasets + +## See Also + +- [Aggregation Strategy

+0800 Subject: [PATCH 21/73] Remove complete time series aggregation example and add data collection service implementation - Deleted `example_complete_series_aggregation.py` as it is no longer needed. - Introduced `data_collection_service.py`, a production-ready service for cryptocurrency market data collection with clean logging and robust error handling. - Added configuration management for multiple trading pairs and exchanges, supporting health monitoring and graceful shutdown. - Created `data_collection.json` for service configuration, including exchange settings and logging preferences. - Updated `CandleProcessingConfig` to reflect changes in timeframes for candle processing. - Enhanced documentation to cover the new data collection service and its configuration,

improved task management and error handling - Implemented enhanced task synchronization to prevent race conditions during WebSocket operations. - Introduced reconnection locking to avoid concurrent reconnection attempts. - Improved error handling in message processing and reconnection logic, ensuring graceful shutdown and task management. - Added unit tests to verify the stability and reliability of the WebSocket client under concurrent operations. --- config/data_collection.json | 2 + data/exchanges/okx/websocket.py | 255 ++++++++++++++------- docs/exchanges/okx_collector.md | 115

Conditional Logging -- **No Logger**: If no logger instance is passed to a component's constructor, that component performs no logging operations -- **Logger Provided**: If a logger instance is passed, the component uses it for logging -- **Error-Only Mode**: If `log_errors_only=True` is set, only error and critical level messages are logged - -### 2. Logger Inheritance -- Components that receive a logger pass the same logger instance down to child components -- This creates a hierarchical logging structure that follows the component hierarchy - -### 3.

self._data_processor = OKXDataProcessor( - symbol, - logger=self.logger # Pass parent's logger - ) -``` - -### Conditional Logging Helpers - -All components use helper methods for conditional logging: - -```python -def _log_debug(self, message: str) -> None: - """Log debug message if logger is available and not in errors-only mode.""" - if self.logger and not self.log_errors_only: - self.logger.debug(message) - -def _log_info(self, message: str) -> None: - """Log info message if logger is available and not in errors-only mode.""" - if self.logger and not self.log_errors_only: - self.logger.info(message) - -def _log_warning(self, message: str) -> None: - """Log warning message if logger is available and not in errors-only mode.""" - if self.logger and not self.log_errors_only: - self.logger.warning(message) - -def _log_error(self, message: str, exc_info: bool = False) -> None: - """Log error message if logger is available (always logs errors).""" - if self.logger: - self.logger.error(message, exc_info=exc_info) - -def _log_critical(self, message: str, exc_info: bool = False) -> None: - """Log critical message if logger is available (always logs critical).""" - if self.logger: - self.logger.critical(message, exc_info=exc_info) -``` - -## Log File Structure - -``` -logs/ -├── collector_manager/ -│ └── 2024-01-15.txt -├── okx_collector_btc_usdt/ -│ └── 2024-01-15.txt -├── okx_collector_eth_usdt/ -│ └── 2024-01-15.txt -└── production_manager/ - └── 2024-01-15.txt -``` - -## Configuration Options - -### Logger Parameters - -- `logger`: Logger instance or None -- `log_errors_only`: Boolean flag for error-only mode -- `verbose`: Console output (when creating new loggers) -- `clean_old_logs`: Automatic cleanup of old log files -- `max_log_files`: Maximum number of log files to keep - -### Environment Variables - -```bash -# Enable verbose console logging -VERBOSE_LOGGING=true - -# Enable console output -LOG_TO_CONSOLE=true -``` - -## Best Practices - -### 1. Component Design -- Always accept `logger=None` parameter in constructors -- Pass logger to all child components -- Use conditional logging helper methods -- Never assume logger is available - -### 2. Error Handling -- Always log errors regardless of `log_errors_only` setting -- Use appropriate log levels -- Include context in error messages - -### 3. Performance -- Conditional logging has minimal performance impact -- Logger checks are fast boolean operations -- No string formatting when logging is disabled - -### 4. Testing -- Test components with and without loggers -- Verify error-only mode works correctly -- Check that child components receive loggers properly - -## Migration Guide - -### Updating Existing Components - -1. **Add logger parameter to constructor**: -```python -def __init__(self, ..., logger=None, log_errors_only=False): -``` - -2. **Add conditional logging helpers**: -```python -def _log_debug(self, message: str) -> None: - if self.logger and not self.log_errors_only: - self.logger.debug(message) -``` - -3. **Update all logging calls**: -```python -# Before -self.logger.info("Message") - -# After -self._log_info("Message") -``` - -4. **Pass logger to child components**: -```python -child = ChildComponent(logger=self.logger) -``` - -### Testing Changes - -```python -# Test without logger -component = MyComponent(logger=None) -# Should work without errors, no logging - -# Test with logger -logger = get_logger('test_component') -component = MyComponent(logger=logger) -# Should log normally - -# Test error-only mode -component = MyComponent(logger=logger, log_errors_only=True) -# Should only log errors -``` - -This conditional logging system provides maximum flexibility while maintaining clean, maintainable code that works in all scenarios. \ No newline at end of file diff --git a/docs/services/data_collection_service.md b/docs/services/data_collection_service.md new file mode 100644 index 0000000..42be79d --- /dev/null +++ b/docs/services/data_collection_service.md @@ -0,0 +1,782 @@ +# Data Collection Service + +The Data Collection Service is a production-ready service for cryptocurrency market data collection with clean logging and robust error handling.

13:56:15 +0800 Subject: [PATCH 29/73] 3.4 -2.0 Indicator Layer System Implementation Implement modular chart layers and error handling for Crypto Trading Bot Dashboard - Introduced a comprehensive chart layer system in `components/charts/layers/` to support various technical indicators and subplots. - Added base layer components including `BaseLayer`, `CandlestickLayer`, and `VolumeLayer` for flexible chart rendering. - Implemented overlay indicators such as `SMALayer`, `EMALayer`, and `BollingerBandsLayer` with robust error handling. - Created subplot layers for indicators like `RSILayer` and `MACDLayer`, enhancing visualization capabilities. - Developed a `MarketDataIntegrator` for seamless data fetching and validation, improving data quality assurance. - Enhanced error handling utilities in `components/charts/error_handling.py` to manage insufficient data scenarios effectively. - Updated documentation to reflect the new chart layer architecture and usage guidelines. - Added unit tests for all chart layer components to ensure functionality and reliability. --- app.py | 110 ++- components/charts/__init__.py | 268 ++++++- components/charts/builder.py | 63 +-

3.0 Strategy Configuration System Implement comprehensive chart configuration and validation system - Introduced a modular chart configuration system in `components/charts/config/` to manage indicator definitions, default configurations, and strategy-specific setups. - Added new modules for error handling and validation, enhancing user guidance and error reporting capabilities. - Implemented detailed schema validation for indicators and strategies, ensuring robust configuration management. - Created example strategies and default configurations to facilitate user onboarding and usage. - Enhanced documentation to provide clear guidelines on the configuration system, validation rules, and usage examples. - Added unit tests for all new components to ensure functionality and reliability across the configuration system. --- components/charts/config/__init__.py | 237 +++++- components/charts/config/defaults.py | 460 +++++++++++ components/charts/config/error_handling.py | 605 ++++++++++++++ .../charts/config/example_strategies.py | 651 +++++++++++++++ components/charts/config/indicator_defs.py | 526 +++++++++++- components/charts/config/strategy_charts.py | 640 +++++++++++++++ components/charts/config/validation.py | 676 ++++++++++++++++ docs/components/charts/README.md | 580 ++++++++++++++ docs/components/charts/configuration.md | 752 ++++++++++++++++++ docs/components/charts/quick-reference.md | 280 +++++++ tasks/3.4.

end of file From 476bd67f144d99d65ddd5bb1598264e952e1c30d Mon Sep 17 00:00:00 2001 From: "Vasily.onl" Date: Wed, 4 Jun 2025 13:01:57 +0800 Subject: [PATCH 31/73] 3.4 Implement user-defined indicator management system and enhance chart capabilities - Introduced a comprehensive user indicator management system in `components/charts/indicator_manager.py`, allowing users to create, edit, and manage custom indicators with JSON persistence. - Added new default indicators in `components/charts/indicator_defaults.py` to provide users with immediate options for technical analysis. - Enhanced the chart rendering capabilities by implementing the `create_chart_with_indicators` function in `components/charts/builder.py`, supporting both overlay and subplot indicators. - Updated the main application layout in `app.py` to include a modal for adding and editing indicators, improving user interaction. - Enhanced documentation to cover the new indicator system, including a quick guide for adding new indicators and detailed usage examples. - Added unit tests to ensure the reliability and functionality of the new indicator management features. --- app.py | 1237 ++++++++++++++++-

Updated `app_new.py` to run the application in debug mode for stability. - Introduced a new time range control panel in `dashboard/components/chart_controls.py`, allowing users to select predefined time ranges and custom date ranges. - Enhanced chart callbacks in `dashboard/callbacks/charts.py` to handle time range inputs, ensuring accurate market statistics and analysis based on user selections. - Implemented logic to preserve chart state during updates, preventing resets of zoom/pan settings. - Updated market statistics display to reflect the selected time range, improving user experience and data relevance. - Added a clear button for custom date ranges to reset selections easily. - Enhanced documentation to reflect the new time range features and usage guidelines. --- app_new.py | 4 +- components/charts/__init__.py | 45 +++-- dashboard/callbacks/charts.py | 254 +++++++++++++++++++++---- dashboard/components/chart_controls.py | 82 +++++++- dashboard/layouts/market_data.py | 8 +- tasks/chart-improvements-immediate.md | 157 +++++++++++++++ tasks/tasks-crypto-bot-prd.md | 26 ++- 7 files changed, 521 insertions(+), 55 deletions(-) create mode 100644 tasks/chart-improvements-immediate.md diff --git a/app_new.py b/app_new.py index dd1ca44..6d095cb 100644 --- a/app_new.py +++ b/app_new.py @@ -32,8 +32,8 @@ def main(): logger.info("Dashboard application initialized successfully") -

Enhanced the `UserIndicator` class to include an optional `timeframe` attribute for custom indicator timeframes. - Updated the `get_indicator_data` method in `MarketDataIntegrator` to fetch and calculate indicators based on the specified timeframe, ensuring proper data alignment and handling. - Modified the `ChartBuilder` to pass the correct DataFrame for plotting indicators with different timeframes. - Added UI elements in the indicator modal for selecting timeframes, improving user experience. - Updated relevant JSON templates to include the new `timeframe` field for all indicators. - Refactored the `prepare_chart_data` function to ensure it returns a DataFrame with a `DatetimeIndex` for consistent calculations. This commit enhances the flexibility and usability of the indicator system, allowing users to analyze data across various timeframes. --- components/charts/builder.py | 17 +- components/charts/data_integration.py | 56 +++++- components/charts/indicator_manager.py | 28 ++- components/charts/utils.py | 7 +- .../templates/bollinger_bands_template.json | 8 +- config/indicators/templates/ema_template.json | 6 + .../indicators/templates/macd_template.json | 11 +- config/indicators/templates/rsi_template.json | 6 + config/indicators/templates/sma_template.json | 6 + .../user_indicators/ema_b869638d.json | 20 ++ .../user_indicators/ema_bfbf3a1d.json | 20 ++ .../user_indicators/macd_307935a7.json | 3 +- dashboard/callbacks/indicators.py | 60 +++--- dashboard/components/data_analysis.py | 21 +- dashboard/components/indicator_modal.py | 21 ++ data/common/indicators.py | 110 +++++----- docs/components/technical-indicators.md | 190 +++++++----------- tasks/tasks-indicator-timeframe-feature.md | 38 ++++ tasks/tasks-refactor-indicator-calculation.md | 36 ++++ 19 files changed, 417 insertions(+), 247 deletions(-) create mode 100644 config/indicators/user_indicators/ema_b869638d.json create mode 100644 config/indicators/user_indicators/ema_bfbf3a1d.json create mode 100644 tasks/tasks-indicator-timeframe-feature.md create mode 100644 tasks/tasks-refactor-indicator-calculation.md diff --git a/components/charts/builder.py b/components/charts/builder.py index a2eca6c..968938a 100644 --- a/components/charts/builder.py +++ b/components/charts/builder.py @@ -489,7 +489,12 @@ class ChartBuilder: if all_indicator_configs: indicator_data_map = self.data_integrator.get_indicator_data( -

SQLAlchemy is used as the ORM. +- **Real-time Messaging**: Redis is used for pub/sub messaging, intended for real-time data distribution between components (though its use in the dashboard is currently deferred). +- **Dashboard & API**: A Dash application serves as the main user interface for visualization, bot management, and system monitoring. The underlying Flask server can be extended for REST APIs. +- **Strategy Engine & Bot Manager**: (Not yet implemented) This component will be responsible for executing trading logic, managing bot lifecycles, and tracking virtual portfolios. +- **Backtesting Engine**: (Not yet implemented) This will provide capabilities to test strategies against historical data. + +### Data Flow +1. The `DataCollectionService` connects to the OKX WebSocket API. +2. Raw trade data is received and processed by `OKXDataProcessor`. +3. Trades are aggregated into OHLCV candles (1m, 5m, etc.). +4. Both raw trade data and processed OHLCV candles are stored in the PostgreSQL database. +5. (Future) The Strategy Engine will consume OHLCV data to generate trading signals. +6. The Dashboard reads data from the database to provide visualizations and system health monitoring. + +## 2. Technology Stack + +- **Backend**: Python 3.10+ +- **Web Framework**: Dash with Dash Bootstrap Components for the frontend UI. +- **Database**: PostgreSQL 14+. SQLAlchemy for ORM. Alembic for migrations. +- **Messaging**: Redis for pub/sub. +- **Data & Numerics**: pandas for data manipulation (especially in backtesting). +- **Package Management**: `uv` +- **Containerization**: Docker and Docker Compose for setting up the development environment (PostgreSQL, Redis, etc.). + +## 3. Coding Conventions + +- **Modular Design**: Code is organized into modules with a clear purpose (e.g., `data`, `database`, `dashboard`). See `architecture.md` for more details. +- **Naming Conventions**: + - **Classes**: `PascalCase` (e.g., `MarketData`, `BaseDataCollector`). + - **Functions & Methods**: `snake_case` (e.g., `get_system_health_layout`, `connect`). + - **Variables & Attributes**: `snake_case` (e.g., `exchange_name`, `_ws_client`). + - **Constants**: `UPPER_SNAKE_CASE` (e.g., `MAX_RECONNECT_ATTEMPTS`). + - **Modules**: `snake_case.py` (e.g., `collector_manager.py`). + - **Private Attributes/Methods**: Use a single leading underscore `_` (e.g., `_process_message`). Avoid double underscores unless for name mangling in classes. +- **File Organization & Code Structure**: + - **Directory Structure**: Top-level directories separate major concerns (`data`, `database`, `dashboard`, `strategies`). Sub-packages should be used for further organization (e.g., `data/exchanges/okx`). + - **Module Structure**: Within a Python module (`.py` file), the preferred order is: + 1. Module-level docstring explaining its purpose. + 2. Imports (see pattern below). + 3. Module-level constants (`ALL_CAPS`). + 4. Custom exception classes. + 5. Data classes or simple data structures. + 6. Helper functions (if any, typically private `_helper()`). + 7. Main business logic classes. + - **`__init__.py`**: Use `__init__.py` files to define a package's public API and simplify imports for consumers of the package. +- **Import/Export Patterns**: + - **Grouping**: Imports should be grouped in the following order, with a blank line between each group: + 1. Standard library imports (e.g., `asyncio`, `datetime`). + 2. Third-party library imports (e.g., `dash`, `sqlalchemy`). + 3. Local application imports (e.g., `from utils.logger import get_logger`). + - **Style**: Use absolute imports (`from data.base_collector import ...`) over relative imports (`from ..base_collector import ...`) for better readability and to avoid ambiguity. + - **Exports**: To create a clean public API for a package, import the desired classes/functions into the `__init__.py` file. This allows users to import directly from the package (e.g., `from data.exchanges import ExchangeFactory`) instead of from the specific submodule. +- **Abstract Base Classes**: Used to define common interfaces, as seen in `data/base_collector.py`. +- **Configuration**: Bot and strategy parameters are managed via JSON files in `config/`. Centralized application settings are handled by `config/settings.py`. +- **Logging**: A unified logging system is available in `utils/logger.py` and should be used across all components for consistent output. +- **Type Hinting**: Mandatory for all function signatures (parameters and return values) for clarity and static analysis. +- **Error Handling**: Custom, specific exceptions should be defined (e.g., `DataCollectorError`). Use `try...except` blocks to handle potential failures gracefully and provide informative error messages. +- **Database Access**: A `DatabaseManager` in `database/connection.py` provides a centralized way to handle database sessions and connections. All database operations should ideally go through an operations/repository layer. + +## 4. Current Implementation Status + +### Completed Features +- **Database Foundation**: The database schema is fully defined in `database/models.py` and `database/schema_clean.sql`, with all necessary tables, indexes, and relationships. Database connection management is robust. +- **Data Collection System**: A highly robust and asynchronous data collection service is in place. It supports OKX, handles WebSocket connections, processes data, aggregates OHLCV candles, and stores data reliably. It features health monitoring and automatic restarts. +- **Basic Dashboard**: A functional dashboard exists. + - **System Health Monitoring**: A comprehensive page shows the real-time status of the data collection service, database, Redis, and system performance (CPU/memory). + - **Data Visualization**: Price charts with technical indicator overlays are implemented. + +### Work in Progress / To-Do +The core business logic of the application is yet to be implemented. The main remaining tasks are: +- **Strategy Engine and Bot Management (Task Group 4.0)**: + - Designing the base strategy interface. + - Implementing bot lifecycle management (create, run, stop). + - Signal generation and virtual portfolio tracking. +- **Advanced Dashboard Features (Task Group 5.0)**: + - Building the UI for managing bots and configuring strategies. +- **Backtesting Engine (Task Group 6.0)**: + - Implementing the engine to test strategies on historical data. +- **Real-Time Trading Simulation (Task Group 7.0)**: + - Executing virtual trades based on signals. + +The project has a solid foundation. The next phase of development should focus on implementing the trading logic and user-facing bot management features. \ No newline at end of file diff --git a/tasks/tasks-crypto-bot-prd.md b/tasks/PRD-tasks.md similarity index 70% rename from tasks/tasks-crypto-bot-prd.md rename to tasks/PRD-tasks.md index 496bc9a..3a7a789 100644 --- a/tasks/tasks-crypto-bot-prd.md +++ b/tasks/PRD-tasks.md @@ -1,5 +1,6 @@ ## Relevant Files +- `CONTEXT.md` -

-## Health Monitoring - -### Monitoring Levels - -The system provides multi-level health monitoring: - -1. **Individual Collector Health** - - Heartbeat monitoring (message loop activity) - - Data freshness (time since last data received) - - Connection state monitoring - - Error rate tracking - -2. **Manager-Level Health** - - Global health checks across all collectors - - Coordinated restart management - - System-wide performance metrics - - Resource utilization monitoring - -### Health Check Intervals - -- **Individual Collector**: Configurable per collector (default: 30s) -- **Global Manager**: Configurable for manager (default: 60s) -- **Heartbeat Updates**: Updated with each message loop iteration -- **Data Freshness**: Updated when data is received - -### Auto-Restart Triggers - -Collectors are automatically restarted when: - -1. **No Heartbeat**: Message loop becomes unresponsive -2. **Stale Data**: No data received within configured timeout -3. **Connection Failures**: WebSocket or API connection lost -4. **Error Status**: Collector enters ERROR or UNHEALTHY state -5. **Manual Trigger**: Explicit restart request - -### Failure Handling - -```python -# Configure failure handling with conditional logging -from utils.logger import get_logger - -logger = get_logger('my_collector', verbose=True) - -collector = MyCollector( - symbols=["BTC-USDT"], - auto_restart=True, # Enable auto-restart - health_check_interval=30.0, # Check every 30 seconds - logger=logger, # Enable logging - log_errors_only=False # Log all levels -) - -# The collector will automatically: -# 1. Detect failures within 30 seconds -# 2. Attempt reconnection with exponential backoff -# 3. Restart up to 5 times (configurable) -# 4. Log all recovery attempts (if logger provided) -# 5. Report status to manager -``` - -## Configuration - -### Environment Variables - -The system respects these environment variables: - -```bash -# Logging configuration (see logging.md for details) -VERBOSE_LOGGING=true # Enable console logging -LOG_TO_CONSOLE=true # Alternative verbose setting - -# Health monitoring -DEFAULT_HEALTH_CHECK_INTERVAL=30 # Default health check interval (seconds) -MAX_SILENCE_DURATION=300 # Max time without data (seconds) -MAX_RECONNECT_ATTEMPTS=5 # Maximum reconnection attempts -RECONNECT_DELAY=5 # Delay between reconnect attempts (seconds) -``` - -### Programmatic Configuration - -```python -from utils.logger import get_logger - -# Configure individual collector with conditional logging -logger = get_logger('custom_collector', verbose=True) - -collector = MyCollector( - exchange_name="custom_exchange", - symbols=["BTC-USDT", "ETH-USDT"], - data_types=[DataType.TICKER, DataType.TRADE], - auto_restart=True, - health_check_interval=15.0, # Check every 15 seconds - logger=logger, # Enable logging - log_errors_only=False # Log all message types -) - -# Configure manager with conditional logging -manager_logger = get_logger('production_manager', verbose=False) -manager = CollectorManager( - manager_name="production_manager", - global_health_check_interval=30.0, # Global checks every 30s - restart_delay=10.0, # 10s delay between restarts - logger=manager_logger, # Manager logging - log_errors_only=True # Only log errors for manager -) - -# Configure specific collector in manager -config = CollectorConfig( - name="primary_okx", - exchange="okx", - symbols=["BTC-USDT", "ETH-USDT", "SOL-USDT"], - data_types=["ticker", "trade", "orderbook"], - auto_restart=True, - health_check_interval=20.0, - enabled=True -) - -manager.add_collector(collector, config) -``` - -## Best Practices - -### 1.

Memory Leaks - -**Symptoms**: Increasing memory usage over time - -**Solutions**: -```python -# Implement proper cleanup with logging -class CleanCollector(BaseDataCollector): - async def disconnect(self): - """Ensure proper cleanup.""" - self._log_info("Starting cleanup process") - - # Clear buffers - if hasattr(self, 'message_buffer'): - self.message_buffer.clear() - self._log_debug("Cleared message buffer") - - # Close connections - if self.websocket: - await self.websocket.close() - self.websocket = None - self._log_debug("Closed WebSocket connection") - - # Clear callbacks - for callback_list in self._data_callbacks.values(): - callback_list.clear() - self._log_debug("Cleared callbacks") - - await super().disconnect() - self._log_info("Cleanup completed") -``` - -## Exchange Factory System - -### Overview - -The Exchange Factory system provides a standardized way to create data collectors for different exchanges. It implements the factory pattern to abstract the creation logic and provides a consistent interface across all exchanges. - -### Exchange Registry - -The system maintains a registry of supported exchanges and their capabilities: - -```python -from data.exchanges import get_supported_exchanges, get_exchange_info - -# Get all supported exchanges -exchanges = get_supported_exchanges() -print(f"Supported exchanges: {exchanges}") # ['okx'] - -# Get exchange information -okx_info = get_exchange_info('okx') -print(f"OKX pairs: {okx_info['supported_pairs']}") -print(f"OKX data types: {okx_info['supported_data_types']}") -``` - -### Factory Configuration - -```python -from data.exchanges import ExchangeCollectorConfig, ExchangeFactory -from data.base_collector import DataType -from utils.logger import get_logger - -# Create configuration with conditional logging -logger = get_logger('factory_collector', verbose=True) - -config = ExchangeCollectorConfig( - exchange='okx', # Exchange name - symbol='BTC-USDT', # Trading pair - data_types=[DataType.TRADE, DataType.ORDERBOOK], # Data types - auto_restart=True, # Auto-restart on failures - health_check_interval=30.0, # Health check interval - store_raw_data=True, # Store raw data for debugging - custom_params={ # Exchange-specific parameters - 'ping_interval': 25.0, - 'max_reconnect_attempts': 5 - } -) - -# Validate configuration -is_valid = ExchangeFactory.validate_config(config) -if is_valid: - collector = ExchangeFactory.create_collector(config, logger=logger) -``` - -### Exchange Capabilities - -Query what each exchange supports: - -```python -from data.exchanges import ExchangeFactory - -# Get supported trading pairs -okx_pairs = ExchangeFactory.get_supported_pairs('okx') -print(f"OKX supports: {okx_pairs}") - -# Get supported data types -okx_data_types = ExchangeFactory.get_supported_data_types('okx') -print(f"OKX data types: {okx_data_types}") -``` - -### Convenience Functions - -Each exchange provides convenience functions for easy collector creation: - -```python -from data.exchanges import create_okx_collector -from utils.logger import get_logger - -# Quick OKX collector creation with logging -logger = get_logger('okx_btc_usdt', verbose=True) - -collector = create_okx_collector( - symbol='BTC-USDT', - data_types=[DataType.TRADE, DataType.ORDERBOOK], - auto_restart=True, - logger=logger -) -``` - -## OKX Implementation - -### OKX Collector Features - -The OKX collector provides: - -- **Real-time Data**: Live trades, orderbook, and ticker data -- **Single Pair Focus**: Each collector handles one trading pair for better isolation -- **Ping/Pong Management**: OKX-specific keepalive mechanism with proper format -- **Raw Data Storage**: Optional storage of raw OKX messages for debugging -- **Connection Resilience**: Robust reconnection logic for OKX WebSocket -- **Conditional Logging**: Full integration with the logging system - -### OKX Usage Examples - -```python -from utils.logger import get_logger - -# Direct OKX collector usage with conditional logging -logger = get_logger('okx_collector', verbose=True) - -collector = OKXCollector( - symbol='BTC-USDT', - data_types=[DataType.TRADE, DataType.ORDERBOOK], - auto_restart=True, - health_check_interval=30.0, - store_raw_data=True, - logger=logger, # Enable logging - log_errors_only=False # Log all levels -) - -# Factory pattern usage with error-only logging -error_logger = get_logger('okx_critical', verbose=False) - -collector = create_okx_collector( - symbol='BTC-USDT', - data_types=[DataType.TRADE, DataType.ORDERBOOK], - logger=error_logger, - log_errors_only=True # Only log errors -) - -# Multiple collectors with different logging strategies -configs = [ - ExchangeCollectorConfig('okx', 'BTC-USDT', [DataType.TRADE]), - ExchangeCollectorConfig('okx', 'ETH-USDT', [DataType.ORDERBOOK]) -] - -collectors = [] -for config in configs: - # Different logging for each collector - if config.symbol == 'BTC-USDT': - logger = get_logger('okx_btc', verbose=True) # Full logging - else: - logger = get_logger('okx_eth', verbose=False, log_errors_only=True) # Errors only - - collector = ExchangeFactory.create_collector(config, logger=logger) - collectors.append(collector) -``` - -### OKX Data Processing - -The OKX collector processes three main data types: - -#### Trade Data -```python -# OKX trade message format -{ - "arg": {"channel": "trades", "instId": "BTC-USDT"}, - "data": [{ -

Key issues included: +- Business logic mixed with data fetching. +- Inconsistent timestamp handling. +- No clear strategy for handling sparse data, leading to potential future data leakage. + +A refactor was necessary to create a modular, extensible, and robust data processing pipeline that aligns with industry standards. + +## Decision +We will refactor the data processing system to adhere to the following principles: + +1. **Modular & Extensible Design**: Separate exchange-specific logic from the core aggregation and storage logic using a factory pattern and base classes. +2. **Right-Aligned Timestamps**: Adopt the industry standard for OHLCV candles where the timestamp represents the closing time of the interval. This ensures compatibility with major exchanges and historical data providers. +3. **Sparse Candle Aggregation**: Emit candles only when trading activity occurs within a time bucket. This accurately reflects market activity and reduces storage. +4. **No Future Leakage**: Implement a robust aggregation mechanism that only finalizes candles when their time period has definitively passed, preventing lookahead bias. +5. **Centralized Repository for Database Operations**: Abstract all database interactions into a `Repository` pattern to decouple business logic from data persistence. + +## Consequences + +### Positive +- **Improved Maintainability**: Code is cleaner, more organized, and easier to understand. +- **Enhanced Extensibility**: Adding new exchanges is significantly easier. +- **Data Integrity**: Standardized timestamping and aggregation prevent data inconsistencies and lookahead bias. +- **Efficiency**: The sparse candle approach reduces storage and processing overhead. +- **Testability**: Decoupled components are easier to unit test. + +### Negative +- **Initial Development Overhead**: The refactor required an initial time investment to design and implement the new architecture. +- **Increased Complexity**: The new system has more moving parts (factories, repositories), which may have a slightly steeper learning curve for new developers. + +## Alternatives Considered + +1. **Keep the Monolithic Design**: Continue with the tightly coupled approach. + - **Reason for Rejection**: This was not scalable and would have led to significant technical debt as new exchanges were added. +2. **Use a Third-Party Data Library**: Integrate a library like `ccxt` for data collection. + - **Reason for Rejection**: While powerful, these libraries did not offer the fine-grained control over the real-time aggregation and WebSocket handling that was required.

This is a component-level implementation pattern, not a feature of `get_logger`. +3. **Logger Inheritance**: Parent components can pass their logger instance to child components, ensuring a consistent logging context. + +### Example: Component Constructor + +All major components should follow this pattern to support conditional logging. + +```python +class ComponentExample: + def __init__(self, logger=None, log_errors_only=False): + self.logger = logger + self.log_errors_only = log_errors_only + + def _log_info(self, message: str) -> None: + """Log info message if logger is available and not in errors-only mode.""" + if self.logger and not self.log_errors_only: + self.logger.info(message) + + def _log_error(self, message: str, exc_info: bool = False) -> None: + """Log error message if logger is available.""" + if self.logger: + self.logger.error(message, exc_info=exc_info) + + # ... other helper methods for debug, warning, critical ... +``` + +This pattern decouples the component's logic from the global logging configuration and makes its logging behavior explicit and easy to manage. + +## Troubleshooting + +- **Permissions**: Ensure the application has write permissions to the `logs/` directory. +- **No Logs**: If file logging fails (e.g., due to permissions), a warning is printed to the console. If `verbose` is not enabled, no further logs will be produced. Ensure the `logs/` directory is writable. +- **Console Spam**: If the console is too noisy, set `verbose=False` when calling `get_logger` and ensure `VERBOSE_LOGGING` is not set to `true` in your environment. + ## Best Practices ### 1.

Standardize database operations to use SQLAlchemy ORM - Updated the `MarketDataRepository` and `RawTradeRepository` classes to exclusively utilize SQLAlchemy ORM for all database interactions, enhancing maintainability and type safety. - Removed raw SQL queries in favor of ORM methods, ensuring a consistent and database-agnostic approach across the repository layer. - Revised documentation to reflect these changes, emphasizing the importance of using the ORM for database operations. These modifications improve the overall architecture of the database layer, making it more scalable and easier to manage. --- CONTEXT.md | 2 +- .../repositories/market_data_repository.py | 169 ++++++++---------- database/repositories/raw_trade_repository.py | 103 +++++------ docs/modules/database_operations.md | 2 + 4 files changed, 122 insertions(+), 154 deletions(-) diff --git a/CONTEXT.md b/CONTEXT.md index c7873b9..1fc83cc 100644 --- a/CONTEXT.md +++ b/CONTEXT.md @@ -65,7 +65,7 @@ The platform is a **monolithic application** built with Python, designed for rap - **Logging**: A unified logging system is available in `utils/logger.py` and should be used across all components for consistent output. - **Type Hinting**: Mandatory for all function signatures (parameters and return values) for clarity and static analysis. - **Error Handling**: Custom, specific exceptions should be defined (e.g., `DataCollectorError`).

From fe9d8e75ed3977fb514322dbd297723c2d35243b Mon Sep 17 00:00:00 2001 From: "Vasily.onl" Date: Sat, 7 Jun 2025 00:27:17 +0800 Subject: [PATCH 59/73] Refactor Redis management and enhance system health callbacks - Replaced the `RedisManager` class with a more modular `SyncRedisManager` and `AsyncRedisManager`, improving the separation of synchronous and asynchronous operations. - Updated the `system_health.py` callbacks to utilize the new `get_sync_redis_manager` function for Redis interactions, simplifying the connection process. - Enhanced error handling and logging in Redis status checks, providing clearer feedback on connection issues. - Revised the setup documentation to reflect changes in Redis connection testing, ensuring clarity for users. These updates improve the maintainability and reliability of Redis interactions within the system, aligning with best practices for modular design. --- dashboard/callbacks/system_health.py | 59 ++- database/redis_manager.py | 555 +++++++++------------------ docs/guides/setup.md | 35 +- tests/database/test_redis_manager.py | 108 ++++++ 4 files changed, 344 insertions(+), 413 deletions(-) create mode 100644 tests/database/test_redis_manager.py diff --git a/dashboard/callbacks/system_health.py b/dashboard/callbacks/system_health.py index 15a63ad..4c06f82 100644 --- a/dashboard/callbacks/system_health.py +++ b/dashboard/callbacks/system_health.py @@ -12,7 +12,7 @@ from dash import Output, Input, State, html, callback_context, no_update import dash_bootstrap_components as dbc from utils.logger import get_logger from database.connection import DatabaseManager -from database.redis_manager import RedisManager +from database.redis_manager import get_sync_redis_manager logger = get_logger("system_health_callbacks") @@ -235,13 +235,16 @@ def _get_database_quick_status() -> dbc.Badge: def _get_redis_quick_status() -> dbc.Badge: """Get quick Redis status.""" try: - redis_manager = RedisManager() + redis_manager = get_sync_redis_manager() redis_manager.initialize() - if redis_manager.test_connection(): + # This check is simplified as initialize() would raise an error on failure. + # For a more explicit check, a dedicated test_connection could be added to SyncRedisManager. + if redis_manager.client.ping(): return dbc.Badge("Connected", color="success", className="me-1") else: return dbc.Badge("Error", color="danger", className="me-1") - except: + except Exception as e: + logger.error(f"Redis quick status check failed: {e}") return dbc.Badge("Error", color="danger", className="me-1") @@ -418,38 +421,52 @@ def _get_database_statistics() -> html.Div: def _get_redis_status() -> html.Div: - """Get Redis status.""" + """Get detailed Redis server status.""" try: - redis_manager = RedisManager() + redis_manager = get_sync_redis_manager() redis_manager.initialize() - info = redis_manager.get_info() + + if not redis_manager.client.ping(): + raise ConnectionError("Redis server is not responding.") + + info = redis_manager.client.info() + status_badge = dbc.Badge("Connected", color="success", className="me-1") return html.Div([ - dbc.Row([ - dbc.Col(dbc.Badge("Redis Connected", color="success"), width="auto"), - dbc.Col(f"Checked: {datetime.now().strftime('%H:%M:%S')}", className="text-muted") - ], align="center", className="mb-2"), - html.P(f"Host: {redis_manager.config.host}:{redis_manager.config.port}", className="mb-0") + html.H5("Redis Status"), + status_badge, + html.P(f"Version: {info.get('redis_version', 'N/A')}"), + html.P(f"Mode: {info.get('redis_mode', 'N/A')}") ]) - except Exception as e: - return dbc.Alert(f"Error connecting to Redis: {e}", color="danger") + logger.error(f"Failed to get Redis status: {e}") + return html.Div([ + html.H5("Redis Status"), + dbc.Badge("Error", color="danger", className="me-1"), + dbc.Alert(f"Error: {e}", color="danger", dismissable=True) + ]) def _get_redis_statistics() -> html.Div: - """Get Redis statistics.""" + """Get detailed Redis statistics.""" try: - redis_manager = RedisManager() + redis_manager = get_sync_redis_manager() redis_manager.initialize() - info = redis_manager.get_info() + + if not redis_manager.client.ping(): + raise ConnectionError("Redis server is not responding.") + + info = redis_manager.client.info() return html.Div([ - dbc.Row([dbc.Col("Memory Used:"), dbc.Col(info.get('used_memory_human', 'N/A'), className="text-end")]), - dbc.Row([dbc.Col("Connected Clients:"), dbc.Col(info.get('connected_clients', 'N/A'), className="text-end")]), - dbc.Row([dbc.Col("Uptime (hours):"), dbc.Col(f"{info.get('uptime_in_seconds', 0) // 3600}", className="text-end")]) + html.H5("Redis Statistics"), + html.P(f"Connected Clients: {info.get('connected_clients', 'N/A')}"), + html.P(f"Memory Used: {info.get('used_memory_human', 'N/A')}"), + html.P(f"Total Commands Processed: {info.get('total_commands_processed', 'N/A')}") ]) except Exception as e: - return dbc.Alert(f"Error loading Redis stats: {e}", color="danger") + logger.error(f"Failed to get Redis statistics: {e}") + return dbc.Alert(f"Error: {e}", color="danger", dismissable=True) def _get_system_performance_metrics() -> html.Div: diff --git a/database/redis_manager.py b/database/redis_manager.py index 6e9d5e0..68cd157 100644 --- a/database/redis_manager.py +++ b/database/redis_manager.py @@ -1,476 +1,291 @@ """ -Redis Manager for Crypto Trading Bot Platform -Provides Redis connection, pub/sub messaging, and caching utilities +Redis Manager for Crypto Trading Bot Platform. +Provides Redis connection, pub/sub messaging, and caching utilities.

Split the `aggregation.py` file into a dedicated sub-package, improving modularity and maintainability. - Moved `TimeframeBucket`, `RealTimeCandleProcessor`, and `BatchCandleProcessor` classes into their respective files within the new `aggregation` sub-package. - Introduced utility functions for trade aggregation and validation, enhancing code organization. - Updated import paths throughout the codebase to reflect the new structure, ensuring compatibility. - Added safety net tests for the aggregation package to verify core functionality and prevent regressions during refactoring. These changes enhance the overall architecture of the aggregation module, making it more scalable and easier to manage. --- data/common/__init__.py | 13 +- data/common/aggregation.py | 598 ------------------ data/common/aggregation/__init__.py | 34 + data/common/aggregation/batch.py | 153 +++++ data/common/aggregation/bucket.py | 144 +++++ data/common/aggregation/realtime.py | 235 +++++++ data/common/aggregation/utils.py | 78 +++ data/common/transformation.py | 2 +- data/exchanges/okx/data_processor.py | 2 +- .../ADR-001-data-processing-refactor.md | 19 +- docs/modules/technical-indicators.md | 2 +- tasks/refactor-common-package.md | 63 ++ tests/data/common/test_aggregation_safety.py | 231 +++++++ tests/quick_aggregation_test.py | 2 +- tests/test_data_collection_aggregation.py | 2 +- tests/test_real_okx_aggregation.py | 2 +- tests/test_refactored_okx.py | 1 + 17 files changed, 965 insertions(+), 616 deletions(-) delete mode 100644 data/common/aggregation.py create mode 100644 data/common/aggregation/__init__.py create mode 100644 data/common/aggregation/batch.py create mode 100644 data/common/aggregation/bucket.py create mode 100644 data/common/aggregation/realtime.py create mode 100644 data/common/aggregation/utils.py create mode 100644 tasks/refactor-common-package.md create mode 100644 tests/data/common/test_aggregation_safety.py diff --git a/data/common/__init__.py b/data/common/__init__.py index d41ce5c..759fe06 100644 --- a/data/common/__init__.py +++ b/data/common/__init__.py @@ -9,15 +9,14 @@ from .data_types import ( StandardizedTrade, OHLCVCandle, MarketDataPoint, - DataValidationResult -) - -from .aggregation import ( - TimeframeBucket, - RealTimeCandleProcessor, + DataValidationResult, CandleProcessingConfig ) +from .aggregation import TimeframeBucket +# Temporarily import from old location until we move these classes +from .aggregation import RealTimeCandleProcessor + from .transformation import ( BaseDataTransformer, UnifiedDataTransformer, @@ -42,11 +41,11 @@ __all__ = [ 'OHLCVCandle', 'MarketDataPoint', 'DataValidationResult', + 'CandleProcessingConfig', # Aggregation 'TimeframeBucket', 'RealTimeCandleProcessor', - 'CandleProcessingConfig', # Transformation 'BaseDataTransformer', diff --git a/data/common/aggregation.py b/data/common/aggregation.py deleted file mode 100644 index 0e44ce7..0000000 --- a/data/common/aggregation.py +++ /dev/null @@ -1,598 +0,0 @@ -""" -Common aggregation utilities for all exchanges. - -This module provides shared functionality for building OHLCV candles -from trade data, regardless of the source exchange. - -AGGREGATION STRATEGY: -- Uses RIGHT-ALIGNED timestamps (industry standard) -- Candle timestamp = end time of the interval (close time) -- 5-minute candle with timestamp 09:05:00 represents data from 09:00:01 to 09:05:00 -- Prevents future leakage by only completing candles when time boundary is crossed -- Aligns with major exchanges (Binance, OKX, Coinbase) - -PROCESS FLOW: -1.

structure - Introduced a dedicated sub-package for technical indicators under `data/common/indicators/`, improving modularity and maintainability. - Moved `TechnicalIndicators` and `IndicatorResult` classes to their respective files, along with utility functions for configuration management. - Updated import paths throughout the codebase to reflect the new structure, ensuring compatibility. - Added comprehensive safety net tests for the indicators module to verify core functionality and prevent regressions during refactoring. - Enhanced documentation to provide clear usage examples and details on the new package structure. These changes improve the overall architecture of the technical indicators module, making it more scalable and easier to manage. --- components/charts/layers/indicators.py | 3 +- components/charts/layers/subplots.py | 3 +- data/common/indicators/__init__.py | 26 ++ data/common/indicators/result.py | 29 ++ .../technical.py} | 114 +----- data/common/indicators/utils.py | 60 ++++ docs/modules/technical-indicators.md | 128 ++++--- tasks/refactor-common-package.md | 20 +- tests/test_indicators_safety.py | 325 ++++++++++++++++++ 9 files changed, 530 insertions(+), 178 deletions(-) create mode 100644 data/common/indicators/__init__.py create mode 100644 data/common/indicators/result.py rename data/common/{indicators.py => indicators/technical.py} (82%) create mode 100644 data/common/indicators/utils.py create mode 100644 tests/test_indicators_safety.py diff --git a/components/charts/layers/indicators.py b/components/charts/layers/indicators.py index f3fd70d..926be99 100644 --- a/components/charts/layers/indicators.py +++ b/components/charts/layers/indicators.py @@ -17,7 +17,8 @@ from ..error_handling import ( ) from .base import BaseLayer, LayerConfig -from data.common.indicators import TechnicalIndicators, OHLCVCandle +from data.common.indicators import TechnicalIndicators +from data.common.data_types import OHLCVCandle from components.charts.utils import get_indicator_colors from utils.logger import get_logger diff --git a/components/charts/layers/subplots.py b/components/charts/layers/subplots.py index d45de36..fe69eac 100644 --- a/components/charts/layers/subplots.py +++ b/components/charts/layers/subplots.py @@ -14,7 +14,8 @@ from dataclasses import dataclass from .base import BaseChartLayer, LayerConfig from .indicators import BaseIndicatorLayer, IndicatorLayerConfig -from data.common.indicators import TechnicalIndicators, IndicatorResult, OHLCVCandle +from data.common.indicators import TechnicalIndicators, IndicatorResult +from data.common.data_types import OHLCVCandle from components.charts.utils import get_indicator_colors from utils.logger import get_logger from ..error_handling import ( diff --git a/data/common/indicators/__init__.py b/data/common/indicators/__init__.py new file mode 100644 index 0000000..0b9c53b --- /dev/null +++ b/data/common/indicators/__init__.py @@ -0,0 +1,26 @@ +""" +Technical Indicators Package + +This package provides technical indicator calculations optimized for sparse OHLCV data +as produced by the TCP Trading Platform's aggregation strategy. + +IMPORTANT: Handles Sparse Data +- Missing candles (time gaps) are normal in this system +- Indicators properly handle gaps without interpolation +- Uses pandas for efficient vectorized calculations +- Follows right-aligned timestamp convention +""" + +from .technical import TechnicalIndicators +from .result import IndicatorResult +from .utils import ( + create_default_indicators_config, + validate_indicator_config +) + +__all__ = [ + 'TechnicalIndicators', + 'IndicatorResult', + 'create_default_indicators_config', + 'validate_indicator_config' +] \ No newline at end of file diff --git a/data/common/indicators/result.py b/data/common/indicators/result.py new file mode 100644 index 0000000..01786f6 --- /dev/null +++ b/data/common/indicators/result.py @@ -0,0 +1,29 @@ +""" +Technical Indicator Result Container + +This module provides the IndicatorResult dataclass for storing +technical indicator calculation results in a standardized format. +""" + +from dataclasses import dataclass +from datetime import datetime +from typing import Dict, Optional, Any + + +@dataclass +class IndicatorResult: + """ + Container for technical indicator calculation results. + + Attributes: + timestamp: Candle timestamp (right-aligned) + symbol: Trading symbol + timeframe: Candle timeframe + values: Dictionary of indicator values + metadata: Additional calculation metadata + """ + timestamp: datetime + symbol: str + timeframe: str + values: Dict[str, float] + metadata: Optional[Dict[str, Any]] = None \ No newline at end of file diff --git a/data/common/indicators.py b/data/common/indicators/technical.py similarity index 82% rename from data/common/indicators.py rename to data/common/indicators/technical.py index c482f66..61ef887 100644 --- a/data/common/indicators.py +++ b/data/common/indicators/technical.py @@ -18,33 +18,13 @@ Supported Indicators: -

Deleted the `okx_config.json` file as part of the configuration refactor. - Updated `BaseDataCollector` to include an optional `timeframes` parameter for more flexible data collection. - Modified `DataCollectionService` and `OKXCollector` to pass and utilize the new `timeframes` parameter. - Enhanced `ExchangeCollectorConfig` to validate timeframes, ensuring they are provided and correctly formatted. - Updated documentation to reflect the new configurable timeframes feature, improving clarity for users. These changes streamline the configuration process and improve the flexibility of data collection, aligning with project standards for maintainability and usability. --- config/okx_config.json | 69 ------------------------- data/base_collector.py | 10 +++- data/collection_service.py | 4 +- data/exchanges/factory.py | 19 ++++++- data/exchanges/okx/collector.py | 18 ++++++- docs/modules/exchanges/README.md | 18 ++++++- docs/modules/exchanges/exchanges.md | 23 ++++++++- docs/modules/exchanges/okx_collector.md | 13 +++-- 8 files changed, 93 insertions(+), 81 deletions(-) delete mode 100644 config/okx_config.json diff --git a/config/okx_config.json b/config/okx_config.json deleted file mode 100644 index 45b2cb6..0000000 --- a/config/okx_config.json +++ /dev/null @@ -1,69 +0,0 @@ -{ -
