Double Bollinger Bands Strategy with Signals (By Rolwin)

This Double Bollinger Bands Strategy identifies high-probability trading opportunities by using two sets of Bollinger Bands (2 standard deviations & 3 standard deviations). The strategy enters long trades when price crosses above the lower 3SD band and short trades when price crosses below the upper 3SD band. Exits occur at the 2SD bands, ensuring a structured risk-reward approach. It includes visual buy/sell signals, dynamic band plotting, and candle coloring when price touches extreme volatility levels, making it effective for trend and mean-reversion trading.
