Filtered Bollinger Bands By @Tradingade

Script from: TradingViewSwingPrice actionMean reversionReversal

Filtered Bollinger Bands is a strategy seeking reversal points via Bollinger Bands and a Trend filter. For long entries, it requires price to extend beyond the lower band and then closes above it. Shorts are the inverse. A key element is the filter based on the prior day's high or low extremes. Exits hinge on price crossing the bands or predefined percentage gains or losses, with percentage-based exits taking precedence over band-crossing conditions.
