Volatility Regime Shader classifies market volatility into three regimes and shades the chart background accordingly. Instead of comparing ATR to a fixed value, it calculates the percentile rank of the current ATR within a lookback window. A percentile of 90 means the current ATR is higher than 90% of the values in that window, so the reading adapts automatically to any symbol and timeframe.Also recommended: volatility change indicator - similar indicator with strong performance on MetaTrader 4.
Bars at or below the Compression threshold are shaded light blue, and bars at or above the Expansion threshold are shaded light red. Normal bars are left unshaded by default. A label in the upper-right corner shows the current regime and ATR percentile.
The regimes can be used as a filter for other strategies. Compression phases often come before breakouts, so breakout systems can wait for compression before arming. Expansion phases favor trend continuation and wider stops, while mean-reversion entries are usually safer in compression or normal conditions.

Both values are also visible in the Data Window. The values of the forming bar update with price, while alerts use closed bars only.
