What is Mean Reversion?
Mean Reversion draws a central moving average and upper and lower range lines on an MT5 chart. The display uses an orange average with green and red outer lines.
The lines show the configured distance from the average and can help organize stretched price movement. They do not establish that price will return to the center line.
How to use Mean Reversion
Review the outer lines with the moving-average slope, completed candles, and nearby price structure. Strong movement can remain outside a displayed range for extended periods.
Range changes the outer-line distance and MA period changes the central moving-average window.
Where it helps
Upper and lower lines make the configured range visible around the moving average.
The average remains visible between the outer lines.
Range and MA period are the available Inputs.
