Overview
BB Strategy tooba calculates a simple moving average basis along with standard deviation bands. When the closing price crosses above the lower band, it places a long stop order, and when price crosses below the upper band, it places a short stop order. Users can configure the moving average length, multiplier, and allowed trading direction. The script lacks explicit stop-loss and take-profit orders, relying entirely on opposing entries to reverse positions.

The Mean Reversion Strategy Template calculates a baseline mean using SMA, EMA, or VWAP alongside upper and lower deviation bands based on standard deviation, ATR, or percentage offsets. It generates long and short entries when price touches, bounces from, or
This strategy generates buy and sell signals based on Bollinger Band crossovers combined with a simple moving average trend filter. It enters a long position when price crosses above the lower band while trading above the SMA filter line, and enters a short po
