Using Autocorrelation to Measure Signal Dependence Across Time Lags

Summary

The document describes a chart indicator that plots the autocorrelation function for a signal. Autocorrelation compares a signal with a shifted copy of itself, showing how their relationship changes as the time lag varies. In market analysis, such a plot can help inspect whether observations or indicator values exhibit persistence or recurring dependence across lags.

The indicator has one setting: the period used to plot the function. The description provides no formula details, worked example, asset or sampling frequency, or empirical trading results. It explains the basic purpose of the visualization but does not establish how to interpret particular patterns or whether they support a profitable trading rule. Any conclusions would depend on the chosen signal, data interval, and lag range.

Key ideas

• Autocorrelation compares a signal with a time-shifted version of itself.
• The plotted relationship varies across time lags.
• The indicator exposes a period setting for the plotted function.
• The description gives no worked example or evidence that the indicator produces trading profits.
