Combining Z-Score Mean Reversion and Momentum Across Currency Pairs

Summary

The article outlines a multi-symbol Expert Advisor that evaluates mean-reversion and momentum signals separately for each instrument. It calculates a Z-score from price relative to a moving average and standard deviation, and measures momentum as a price change over a chosen lookback. Thresholds determine whether a deviation or move is strong enough to consider a trade; the framework also describes using volatility and risk settings to shape entries and position exposure. The implementation monitors a configurable list of instruments on an hourly timeframe.

The article explains that mean reversion is intended for ranging conditions, while momentum seeks continuation, and warns that persistent trends can undermine reversion trades. It lists backtest settings for a two-month period, but the supplied excerpt gives no performance statistics, benchmark, or out-of-sample evidence. The claimed adaptability therefore remains a design rationale rather than demonstrated robustness. Threshold selection, correlated positions, and regime changes remain important risks when applying the approach.

Key ideas

• The system combines Z-score deviations from a moving average with a separate price-change momentum measure.
• Mean-reversion signals anticipate a return toward the average, while momentum signals follow strong moves.
• Thresholds and per-symbol calculations govern whether the framework considers an entry.
• The article describes a short hourly backtest window but supplies no performance results in the excerpt.
• Persistent trends, correlated exposures, and changing market regimes can weaken the approach.
