[DEM] Bollinger Bands + Rob Hoffman Signal (With Backtesting)

[DEM] Bollinger Bands + Rob Hoffman Signal (With Backtesting) combines Bollinger Bands with a custom price action pattern, reminiscent of Rob Hoffman's "Inventory Retracement Bar" concept, to generate buy and sell signals. It includes a robust backtesting framework to evaluate the historical performance of these signals. The indicator overlays directly on the price chart, plotting signals and displaying performance statistics in a table.
