The Quantitative Qualitative Estimation (QQE) Weighted Oscillator is an advanced technical indicator that enhances the traditional RSI by applying a weighting mechanism influenced by a trailing stop derived from the RSI itself. This design requires greater "effort" for the RSI to cross the trailing stop, potentially filtering out weaker signals. The indicator consists of a smoothed RSI oscillator paired with its trailing stop, enabling it to identify overbought or oversold market conditions and provide early signals of trend reversals due to the leading characteristics of the RSI. Users can adjust key parameters including Length (RSI period), Factor (multiplicative factor for trailing stop calculation), Smooth (degree of RSI smoothing), and Weight (degree of RSI weighting). Higher Factor values produce longer-term trailing stops, while increased Weight values demand stronger price movements to trigger crosses, resulting in smoother and more cyclical oscillator behavior. Like standard RSI, divergence between price and the oscillator may indicate potential reversals. This indicator is categorized under momentum indicators and is primarily based on the Relative Strength Index methodology.
