# Enhanced IncStrategyBase Implementation Summary
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
Successfully implemented **Option 1** - Enhanced `IncStrategyBase` with built-in timeframe aggregation functionality. All incremental strategies now accept minute-level data and internally aggregate to their configured timeframes.
|
||
|
|
|
||
|
|
## Key Achievements
|
||
|
|
|
||
|
|
### ✅ Enhanced Base Class (`cycles/IncStrategies/base.py`)
|
||
|
|
|
||
|
|
**New Components Added:**
|
||
|
|
1. **TimeframeAggregator Class**: Handles real-time aggregation of minute data to higher timeframes
|
||
|
|
2. **update_minute_data() Method**: Standardized interface for minute-level data processing
|
||
|
|
3. **Automatic Timeframe Detection**: Extracts timeframe from strategy parameters
|
||
|
|
4. **Built-in Aggregation**: Seamless minute-to-timeframe conversion
|
||
|
|
|
||
|
|
**Key Features:**
|
||
|
|
- **Consistent Interface**: All strategies now have `update_minute_data()` method
|
||
|
|
- **Automatic Aggregation**: Base class handles OHLCV aggregation internally
|
||
|
|
- **Backward Compatibility**: Existing `update()` methods still work
|
||
|
|
- **Performance Monitoring**: Enhanced metrics for minute data processing
|
||
|
|
- **Memory Efficient**: Constant memory usage with proper cleanup
|
||
|
|
|
||
|
|
### ✅ Updated Strategies
|
||
|
|
|
||
|
|
#### 1. **RandomStrategy** (`cycles/IncStrategies/random_strategy.py`)
|
||
|
|
- **Simplified Implementation**: Removed manual timeframe handling
|
||
|
|
- **Flexible Timeframes**: Works with any timeframe (1min, 5min, 15min, etc.)
|
||
|
|
- **Enhanced Logging**: Shows aggregation status and timeframe info
|
||
|
|
|
||
|
|
#### 2. **MetaTrend Strategy** (`cycles/IncStrategies/metatrend_strategy.py`)
|
||
|
|
- **Streamlined Buffer Management**: Base class handles timeframe aggregation
|
||
|
|
- **Simplified Configuration**: Only specify primary timeframe
|
||
|
|
- **Enhanced Logging**: Shows aggregation status
|
||
|
|
|
||
|
|
#### 3. **BBRS Strategy** (`cycles/IncStrategies/bbrs_incremental.py`)
|
||
|
|
- **Full Compatibility**: Existing implementation works seamlessly
|
||
|
|
- **No Changes Required**: Already had excellent minute-level processing
|
||
|
|
|
||
|
|
## Test Results
|
||
|
|
|
||
|
|
### ✅ Comprehensive Testing (`test_enhanced_base_class.py`)
|
||
|
|
|
||
|
|
**RandomStrategy Results:**
|
||
|
|
- **1min timeframe**: 60 minutes → 60 bars (aggregation disabled, direct processing)
|
||
|
|
- **5min timeframe**: 60 minutes → 11 bars (aggregation enabled, ~12 expected)
|
||
|
|
- **15min timeframe**: 60 minutes → 3 bars (aggregation enabled, ~4 expected)
|
||
|
|
|
||
|
|
**MetaTrend Strategy Results:**
|
||
|
|
- **15min timeframe**: 300 minutes → 19 bars (~20 expected)
|
||
|
|
- **Warmup**: Successfully warmed up after 12 data points
|
||
|
|
- **Aggregation**: Working correctly with built-in TimeframeAggregator
|
||
|
|
|
||
|
|
**BBRS Strategy Results:**
|
||
|
|
- **30min timeframe**: 120 minutes → 3 bars (~4 expected)
|
||
|
|
- **Compatibility**: Existing implementation works perfectly
|
||
|
|
- **No Breaking Changes**: Seamless integration
|
||
|
|
|
||
|
|
## Implementation Details
|
||
|
|
|
||
|
|
### TimeframeAggregator Logic
|
||
|
|
```python
|
||
|
|
# Automatic timeframe boundary calculation
|
||
|
|
bar_start = timestamp.replace(
|
||
|
|
hour=(timestamp.hour * 60 + timestamp.minute) // timeframe_minutes * timeframe_minutes // 60,
|
||
|
|
minute=(timestamp.hour * 60 + timestamp.minute) // timeframe_minutes * timeframe_minutes % 60,
|
||
|
|
second=0, microsecond=0
|
||
|
|
)
|
||
|
|
|
||
|
|
# OHLCV aggregation
|
||
|
|
if new_bar:
|
||
|
|
return completed_bar # Previous bar is complete
|
||
|
|
else:
|
||
|
|
# Update current bar: high=max, low=min, close=current, volume+=current
|
||
|
|
```
|
||
|
|
|
||
|
|
### Timeframe Parameter Detection
|
||
|
|
```python
|
||
|
|
def _extract_timeframe_minutes(self) -> int:
|
||
|
|
# Direct specification: timeframe_minutes=60
|
||
|
|
# String parsing: timeframe="15min", "1h", "2d"
|
||
|
|
# Default: 1 minute for direct processing
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage Examples
|
||
|
|
|
||
|
|
#### Real-time Trading
|
||
|
|
```python
|
||
|
|
# Any strategy with any timeframe
|
||
|
|
strategy = IncRandomStrategy(params={"timeframe": "15min"})
|
||
|
|
|
||
|
|
# Process live minute data
|
||
|
|
for minute_data in live_stream:
|
||
|
|
result = strategy.update_minute_data(timestamp, ohlcv_data)
|
||
|
|
if result is not None: # Complete 15min bar formed
|
||
|
|
entry_signal = strategy.get_entry_signal()
|
||
|
|
exit_signal = strategy.get_exit_signal()
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Multi-timeframe Support
|
||
|
|
```python
|
||
|
|
# Different strategies, different timeframes
|
||
|
|
strategies = [
|
||
|
|
IncRandomStrategy(params={"timeframe": "5min"}),
|
||
|
|
IncMetaTrendStrategy(params={"timeframe": "15min"}),
|
||
|
|
BBRSIncrementalState({"timeframe_minutes": 60})
|
||
|
|
]
|
||
|
|
|
||
|
|
# All accept the same minute-level data
|
||
|
|
for minute_data in stream:
|
||
|
|
for strategy in strategies:
|
||
|
|
result = strategy.update_minute_data(timestamp, minute_data)
|
||
|
|
# Each strategy processes at its own timeframe
|
||
|
|
```
|
||
|
|
|
||
|
|
