Enhanced Real-Time Online Training System
|

This system implements effective online learning with:
|
||||
- High-frequency data integration (COB, ticks, OHLCV)
|
||||
- Proper reward engineering for profitable trading
|
||||
- Experience replay with prioritization
|
||||
- Continuous validation and adaptation
|
||||
- Multi-timeframe feature engineering
|
||||
- Real market microstructure analysis
