Rolling Quantile Indicator Explained

The Rolling Quantile plots any percentile of the recent window — the 80th, the 25th, whatever your logic needs. It generalizes Donchian thinking: instead of the absolute extreme (100th percentile), you can trade the robust extremes that ignore the single wildest ticks.

How It Works

• The chosen percentile of the last N values, each bar.
• The 50th percentile is the median; 0/100 are Donchian rails.
• Pairs of quantiles (20th/80th) form outlier-resistant channels.

How to Trade It

Build robust breakout logic (close above the 90th percentile means more than above the absolute high wick), adaptive profit zones, or asymmetric channels for skewed markets. It's a lego brick — most useful composed with other tools in the Indicators Lab.

Building It in Setup.Cash

Add Rolling Quantile in the strategy builder — the length input controls its sensitivity — and use its value in any entry, exit, or filter condition. You can also combine it with other tools in the Indicators Lab or via the AI indicator generator. See Donchian Channels for the extreme-based classic. For the full category overview, see the volatility & statistics library guide.

Volatility indicators qualify trades rather than generate them — backtest your system with and without this filter and compare the drawdowns.
