Price Z-Score Threshold Crossovers for Long and Short Trading

Summary

This strategy standardizes price relative to an exponential moving average using the rolling standard deviation. Its configurable average and deviation windows, threshold, and trading direction determine how the signal is calculated and which positions can be taken. A long opens when the Z-score crosses above the positive threshold and closes after it crosses below the negative threshold; a short opens on the negative crossing and closes on the positive crossing.

The document provides the signal rules and chart visualizations, but no performance results or market-specific evaluation. It uses example settings and specifies commission, slippage, and position sizing for its strategy configuration, but those assumptions do not establish profitability. The approach can be sensitive to the chosen windows and threshold, and a standardized price move alone does not address changing market regimes or risk limits.

Key ideas

• The Z-score measures price distance from an exponential moving average in rolling standard deviation units.
• A positive threshold crossover opens a long position, while a negative threshold crossover opens a short position when enabled.
• Long and short exits occur at the opposite threshold crossing.
• The strategy exposes its lookback windows, threshold, and permitted trade direction as configurable inputs.
• The document describes the rules but supplies no results demonstrating their performance.
