Overview
Bollinger Bands and Trend EA filters for ranging markets using a long-period EMA slope to execute reversal trades with candlestick confirmation, specifically identifying Doji patterns at the bands. Risk management includes dynamic ATR-based stop losses, fixed take profit targets, and automated breakeven logic. The EA calculates position sizes based on a set risk percentage per trade and includes a trailing stop for its trend-following mode. Volatility filters ensure trades only open during sufficient market movement. The repository lacks a README.
