Z-Score Extremes as Mean-Reversion Signals
Summary
This indicator calculates separate z-scores for recent highs and lows using a 500-candle simple moving average and standard deviation, then averages the two readings. It treats high positive values as potentially overbought and low negative values as potentially oversold. Signals are generated when the combined reading crosses stated thresholds, with a long signal below the lower threshold and a short signal above the upper threshold. The author presents the measure as a way to assess how unusually far price has moved from its recent mean and to monitor a possible reversion.
The discussion frames extreme deviations as increasing the chance of a return toward the average, and mentions use for swing analysis on hourly charts as well as shorter intervals. This is a heuristic, not evidence of predictive power: the document offers no measured results despite including a backtest configuration and image. Extreme readings can persist or grow during strong trends, and the author acknowledges false signals. The indicator is best interpreted as context for analysis rather than a stand-alone guarantee of reversal.
Key ideas
- The indicator averages z-scores calculated from highs and lows over a 500-candle lookback.
- A reading beyond either stated extreme threshold triggers a directional signal toward mean reversion.
- The author describes the measure as an aid for judging overbought and oversold conditions.
- The published material provides no performance statistics to demonstrate signal reliability.
- Extreme deviations can persist, so the indicator can produce false reversal expectations.
