atrLow and atrHigh are calculated as percentiles (20% and 80% by default) of ATR values over the last double the ATR period (28 days if ATR is 14). This creates thresholds that adapt to recent market conditions. Background Heatmap:
Green: ATR is below the low threshold, indicating calm markets (options are cheap). Red: ATR is above the high threshold, signaling elevated volatility (options are expensive). Yellow: ATR is within the normal range, showing neutral market conditions. Overlay Lines:
