QQE (Quantitative Qualitative Estimation) Indicator Explained

QQE (Quantitative Qualitative Estimation) takes a smoothed RSI and wraps it in a volatility-scaled trailing band — essentially an ATR trailing stop applied to the oscillator itself. Signals come from the RSI crossing its own adaptive band, not from fixed 70/30 lines.

How It Works

• RSI is EMA-smoothed, and the volatility of that smoothed RSI sets band width.
• The band trails the RSI like a stop line, flipping when crossed.
• Crosses of the band (and the 50 midline) are the signal events.

How to Trade It

The self-adjusting threshold is QQE's edge: in volatile regimes the band widens and demands bigger moves, in quiet ones it tightens automatically. Trade band crosses as momentum entries or use 'QQE above its band and above 50' as a strong long filter.

Building It in Setup.Cash

Add QQE (Quantitative Qualitative Estimation) 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. Compare with RSX, which attacks RSI noise by filtering instead of banding.
