TL GetActive

This reserved word returns a numeric value representing the ID of the currently active trendline.

TL_GetActive returns -1 if no trendlines are currently selected or were added to a chart yet. If an active trendline is removed from a chart then TL_GetActive returns -1. If an inactive trendline is removed from a chart then TL_GetActive returns the object ID number of the currently active trendline.

Notes

• TL_GetActive should be assigned to a numeric variable or array in order to determine if the operation is performed successfully. In other words, if the returning value of TL_GetActive isn't saved, it's not possible to check whether or not the selection of the trendline succeeded.

Example

Value1 = TL_GetActive;

Assigns the ID of the currently active trendline to the Value1 variable. The variable to which the returning value is assigned can be a numeric variable or numeric array.
