Overview
The robot uses exponential moving averages, specifically the EMA 34 and EMA 89, to determine trend direction and slope thresholds. It executes trend-following trades on initial pullbacks from new highs or lows and includes a counter-trend mode for short-term reversals at support and resistance. Risk management is handled through ATR-based dynamic stop losses, trailing stops, and configurable equity-risk lot sizing. The repository includes multiple sub-systems for different trend strengths, although the README is minimal.
- ATR-based dynamic stop loss and trailing stop
- EMA 34 and 89 slope and crossover analysis
- Trend-following and counter-trend execution modes
- Equity-based risk management and fixed lot sizing
- Time-based filters and spread protection
