Source Code

Overview
A long position opens when the price crosses above the upper Bollinger Band, provided the band spread meets a minimum threshold and price is above the moving average filter. Long positions close when the price drops below the middle basis line. Symmetrical logic applies to short positions. Users can adjust band parameters, spread limits, filter MA types, and backtest date ranges. The script draws directly on the main price chart and lacks hard stop-loss orders.
The inputs you can change from the gear icon on the chart. Defaults are the author's.
