Source Code

Overview
XAUUSD Dollar Trader Martingale BBW Step (SMA 20/50/200) evaluates the alignment of 20, 50, and 200-period SMAs alongside a BBW moving average expansion condition evaluated on closed bars. Position sizing follows a stepped Martingale system that scales position volume up after consecutive losses and steps down on wins, bounded by configurable maximum steps and overshoot controls. Plotted directly on the price chart, the strategy operates without a default hard stop loss.
- Triple SMA trend alignment system
- Bollinger Band Width volatility expansion filter
- Stepped Martingale lot size adjustment
- Configurable overshoot and undershoot tracking
