The Quantitative Qualitative Estimation (QQE) indicator is a technical analysis tool that enhances the Relative Strength Index (RSI) by incorporating smoothed moving averages. It helps traders assess trend strength, potential reversals, and overbought/oversold conditions with greater accuracy.

QQE features two key components: the fast level, which act as dynamic support and resistance, and a signal line to indicate a shift in momentum. This makes it a versatile tool for both trend-following and mean-reversion strategies. A crossover between the QQE line and its signal line often indicates potential buy or sell opportunities.
