ZScore Reversion is a trading indicator that standardizes price data by converting closing prices into Z-Scores, which measure how many standard deviations a price is from its historical mean over a specified lookback period. This transformation highlights statistical extremes near ±1, ±2, or ±3 standard deviations, indicating overbought or oversold conditions and potential high-probability reversal zones.
The indicator calculates the mean and standard deviation of recent closing prices to determine the Z-Score using the formula:
Z = (Current Close − Historical Mean) / Standard Deviation.
Positive Z-Scores indicate prices above the mean, while negative scores indicate prices below it.
ZScore Reversion provides clear visualizations through histograms, special candles, moving averages, and colored zones to distinguish normal price behavior from statistical outliers. It supports mean reversion trading by signaling when prices exceed ±2 or ±3 standard deviations, suggesting a likely return to the mean. It also aids trend confirmation by interpreting sustained positive or negative Z-Scores combined with moving average trends.
Risk management is facilitated by adjusting stops and position sizes near extreme Z-Score values. Entry timing can be refined by combining extreme Z-Scores with support and resistance levels. The indicator offers multiple display modes and customization options for length, colors, and chart types. It is best suited for stable volatility environments and assumes a normal distribution of price data.
