Overview

NostalgiaForInfinityV2 evaluates price behavior using dual Bollinger Bands, RSI, exponential moving averages, and ATR volatility metrics sampled across both chart and 1-hour timeframes. Buy signals trigger when price interacts with lower Bollinger Bands alongside volume and RSI filters, while exits execute upon reaching overbought RSI levels. The indicator overlays plots directly on the main chart. Note that higher-timeframe data causes repainting on lower-timeframe bars and no stop loss is defined by default.

RSI differential and volume mean filters
