Gold EMA Deviation Strategy Using Z-Score Thresholds

Summary

This strategy measures price deviation from a 21-day exponential moving average and standardizes that deviation as a Z-score. It enters long when the score crosses above 0.5 and short when it crosses below -0.5, then exits as the score returns through the relevant entry threshold. The described stops trigger at readings beyond three standard deviations. The method is presented as trend following, using the EMA as a baseline and normalized deviations to make entry and exit thresholds explicit.

The document gives a single EMA length parameter and published backtest settings for a short 4-hour test, but those settings identify Bitcoin futures even though the strategy is titled and explained as a gold strategy. It reports no performance figures. It also cautions that gaps, threshold choices, and abrupt events can cause misleading signals or premature exits; the short test and market mismatch further limit what can be concluded about its suitability for gold.

Key ideas

• The strategy standardizes price distance from a 21-period EMA into a Z-score.
• A cross above 0.5 opens a long, while a cross below -0.5 opens a short.
• Positions close when the Z-score returns through the corresponding threshold, with stops beyond three standard deviations.
• The document identifies gaps, threshold selection, and sudden market moves as risks.
• Published backtest settings specify Bitcoin futures rather than gold and provide no performance results.
