Overview
Bollinger Bands DEMA performs multi-timeframe analysis, referencing the 30-minute chart for volatility envelopes and the daily chart for trend filtering. The robot executes trades using fixed lot sizes and includes logic to process entries only at the start of a new bar. Documentation is absent in the repository, and the code appears to be a basic implementation of indicator-based signals without configurable stop loss or take profit inputs.
- Multi-timeframe indicator analysis
- Bollinger Bands volatility filtering
- Double Exponential Moving Average trend detection
