# Project Context: Simplified Crypto Trading Bot Platform
|
||||
# Project Context: Advanced Crypto Trading Bot Platform
|
||||
|
||||
This document provides a comprehensive overview of the project's architecture, technology stack, conventions, and current implementation status, following the guidelines in `context-management.md`.
|
||||
|
||||
## 1. Architecture Overview
|
||||
|
||||
The platform is a **monolithic application** built with Python, designed for rapid development and internal testing of crypto trading strategies. The architecture is modular, with clear separation between components to facilitate future migration to microservices if needed.
|
||||
The platform is a **monolithic application** built with Python, designed for professional crypto trading strategy development and testing. The architecture features a mature, modular design with production-ready components and clear separation between infrastructure and business logic.
|
||||
|
||||
### Core Components
|
||||
- **Data Collection Service**: A standalone, multi-process service responsible for collecting real-time market data from exchanges (currently OKX). It uses a robust `BaseDataCollector` abstraction and specific exchange implementations (e.g., `OKXCollector`). Data is processed, aggregated into OHLCV candles, and stored.
|
||||
- **Database**: PostgreSQL with the TimescaleDB extension (though currently using a "clean" schema without hypertables for simplicity). It stores market data, bot configurations, trading signals, and performance metrics. 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.
|
||||
|
||||
- **Production-Ready Data Collection Service**: A highly sophisticated, multi-process service with robust error handling, health monitoring, and auto-restart capabilities. Features a `BaseDataCollector` abstraction, `CollectorManager` for coordination, and exchange-specific implementations (OKX). Includes comprehensive telemetry, state management, and connection management.
|
||||
|
||||
- **Enterprise Database Layer**: PostgreSQL with TimescaleDB support, featuring a mature repository pattern implementation. Uses SQLAlchemy ORM with proper connection pooling, session management, and Alembic migrations. Includes specialized repositories for different entities with consistent error handling.
|
||||
|
||||
- **Advanced Dashboard & Visualization**: A sophisticated Dash application with multiple specialized layouts, real-time charting, technical indicator overlays, and comprehensive system monitoring. Features advanced chart configurations, strategy visualization tools, and responsive UI components.
|
||||
|
||||
- **Technical Indicators Engine**: Complete implementation of technical indicators (SMA, EMA, RSI, MACD, Bollinger Bands) with sparse data handling, chart layer integration, and configurable parameters.
|
||||
|
||||
- **Real-time Messaging Infrastructure**: Redis-based pub/sub system for component communication, with organized channel structures and both synchronous and asynchronous support.
|
||||
|
||||
- **Strategy Engine & Bot Manager**: (⚠️ **NOT YET IMPLEMENTED**) Core trading logic components for strategy execution, bot lifecycle management, and virtual portfolio tracking.
|
||||
|
||||
- **Backtesting Engine**: (⚠️ **NOT YET IMPLEMENTED**) Historical strategy testing capabilities.
|
||||
|
||||
### 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.
|
||||
1. **Data Collection**: `DataCollectionService` connects to exchange APIs (OKX WebSocket)
|
||||
2. **Processing**: Raw trade data processed by exchange-specific processors
|
||||
3. **Aggregation**: Trades aggregated into OHLCV candles across multiple timeframes
|
||||
4. **Storage**: Both raw trade data and processed OHLCV stored in PostgreSQL
|
||||
5. **Distribution**: Real-time data distributed via Redis pub/sub channels
|
||||
6. **Visualization**: Dashboard reads from database for charts and system monitoring
|
||||
7. **Strategy Processing**: (Future) Strategy engine will consume OHLCV data for signal generation

||||
## 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.
|
||||
- **Classes**: `PascalCase` (e.g., `MarketData`, `BaseDataCollector`, `CollectorManager`)
|
||||
- **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**: Single underscore `_` prefix
|
||||
|
||||
- **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.
|
||||
- **Repository Pattern**: Database operations centralized through repository classes
|
||||
- **Factory Pattern**: Used for collector creation and management
|
||||
- **Abstract Base Classes**: Well-defined interfaces for extensibility
|
||||
- **Dependency Injection**: Configuration and dependencies injected rather than hardcoded
|
||||
- **Error Handling**: Custom exception hierarchies with proper error context
|
||||
|
||||
- **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**: All database operations must go through the repository layer, accessible via `database.operations.get_database_operations()`. The repositories exclusively use the **SQLAlchemy ORM** for all queries to ensure type safety, maintainability, and consistency. Raw SQL is strictly forbidden in the repository layer to maintain database-agnostic flexibility.
|
||||
- **Absolute imports** preferred over relative imports
|
||||
- **Clean public APIs** exposed through `__init__.py` files
|
||||
- **Grouped imports**: Standard library, third-party, local application
|
||||
|
||||
- **Configuration Management**:
|
||||
- **Pydantic Settings**: Type-safe configuration with environment variable support
|
||||
- **JSON Configuration**: Strategy and bot parameters in JSON files
|
||||
- **Environment Variables**: All credentials and deployment settings via `.env`
|
||||
|
||||
- **Database Access**:
|
||||
- **Repository Pattern**: All database operations through repository layer
|
||||
- **SQLAlchemy ORM**: Exclusive use of ORM for type safety and maintainability
|
||||
- **Connection Pooling**: Sophisticated connection management with monitoring
|
||||
- **Session Management**: Proper session lifecycle with context managers
|
||||
|
||||
- **Logging & Monitoring**:
|
||||
- **Unified Logging**: Component-specific loggers with centralized configuration
|
||||
- **Health Monitoring**: Comprehensive health checks and telemetry
|
||||
- **Error Tracking**: Detailed error context and automated alerts
|
||||
|
||||

## 📋 **File Structure Recommendations**
|
||||
|
||||
### Create Missing Directories
|
||||
```
|
||||
strategies/
|
||||
├── __init__.py
|
||||
├── base_strategy.py
|
||||
├── ema_crossover.py
|
||||
├── macd_strategy.py
|
||||
├── rsi_strategy.py
|
||||
└── factory.py
|
||||
|
||||
bot/
|
||||
├── __init__.py
|
||||
├── manager.py
|
||||
├── instance.py
|
||||
└── portfolio.py
|
||||
|
||||
backtesting/
|
||||
├── __init__.py
|
||||
├── engine.py
|
||||
├── performance.py
|
||||
└── results.py
|
||||
```
|
||||
|
||||
### Refactor Large Files
|
||||
- Break `data/collector/base_collector.py` into:
|
||||
- `base_collector.py` (abstract interface)
|
||||
- `collector_telemetry.py` (monitoring)
|
||||
- `collector_health.py` (health checks)
|
||||
|
||||
## 🎉 **Conclusion**
|
||||
|
||||
The TCP Dashboard project has evolved into a sophisticated trading infrastructure platform with production-ready data collection, advanced visualization, and enterprise-grade database management. The foundation is excellent for implementing trading strategies.
|
||||
|
||||
**Next Phase Focus**: Implement core business logic (strategies, bot management, backtesting) on top of the solid infrastructure foundation.
|
||||
|
||||
**Timeline Estimate**:
|
||||
- Strategy Engine: 1-2 weeks
|
||||
- Bot Management: 2-3 weeks
|
||||
- Backtesting Engine: 2-3 weeks
|
||||
- Integration & Testing: 1-2 weeks
|
||||
|
||||
**Total**: 6-10 weeks to complete core trading functionality
