Using this tool involves drawing a line. To do this, left click on the chart with your Pointer to mark point A, move the Pointer and left click again to mark point B. The line A-B represents the length of price move.

The expansion/extension levels are calculated from these 2 points. If the line is down sloping, then the expansion lines will move downward starting from 0% at the bottommost point and the percentages will increase from this bottommost point. If the line is up sloping, then the retracement lines will move upwards starting from 0% at the topmost point and the percentages will increase from this topmost point.
