Multi-Timeframe Prediction System for Enhanced Trading
This module implements a sophisticated multi-timeframe prediction system that allows
models to make predictions for different time horizons (1, 5, 10 minutes) with
appropriate confidence thresholds and position holding strategies.
Key Features:
- Dynamic sequence length adaptation for different timeframes
- Confidence calibration based on prediction horizon
- Position holding logic for longer-term trades
- Risk-adjusted trading strategies
