The QQE (Quantitative Qualitative Estimator) indicator consists of a smoothed Relative Strength Index (RSI) indicator and two volatility-based trailing levels (fast and slow).

Compared to the original QQE indicator this version is adding:

• Fixed levels (to help further estimate the trend).
• Color changing histogram (based on those levels).

This way we have some more information available to analyze.

This version is also using RSX (a smoother RSI without a lag) in order to further purify the signals.
