This line allows you to see the probable starting point of the wave sequence along with a sufficient number of bars displayed in the chart. It also makes the wave labeling easier for the price history of an instrument displayed on the selected timeframe.
The indicator can automatically choose a required lower timeframe considering 140-150 bars that should be displayed. To do it, select the required area on the chart using a rectangle and then double click with the mouse on a line of the rectangle.
