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

# 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

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

# 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

# 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
