Measuring Price Deviation from an Exponential Moving Average

Summary

This document presents a simple indicator for measuring how far the current closing price sits, in percentage terms, from an exponential moving average. It calculates the average over a configurable period, then expresses the difference between the close and the average as a percentage of the close. The output is plotted against a zero line and user-defined upper and lower reference levels.

The example supplies a period of 200 and reference levels at positive and negative 15 percent, but it offers no rationale for those choices. It contains no trading rules, historical tests, market examples, or evidence that particular deviations forecast reversals or continuation. The measure can help quantify price extension relative to a smoothed baseline, but interpretation depends on the asset, timeframe, and parameter choices. The document does not explain whether the measure is intended for mean-reversion, trend analysis, or another use.

Key ideas

• The indicator measures the close's percentage distance from an exponential moving average.
• The averaging period and upper and lower reference levels are configurable.
• The example uses a 200-period average and reference levels of positive and negative 15 percent.
• The document provides no trading interpretation or evidence of predictive performance.
