Overview
PineForge — Ledger History NA enters a long position when price crosses under an entry threshold set below the smoothed anchor. The trade closes when price crosses back above the anchor level. Downside risk is managed with an ATR-based stop loss below the average entry price, sized at six percent of equity. User settings adjust lookback length, smoothing period, deviation percentage, and stop values. The system only takes long trades.
- Smoothed historical anchor line
- Deviation entry threshold
- ATR-based stop loss
- Mean-reversion crossover exit

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
