Returns a logical value, indicating whether the trendline with the specified ID number is extended to the left; returns a value of [[True]] if the trendline is extended, and a value of [[False]] if the trendline is not extended or if the specified trendline ID number is invalid.
==== Usage ====
<syntaxhighlight>TL_GetExtLeft(TL_ID)</syntaxhighlight>
Where: [[TL_ID]] - a numerical expression specifying the trendline ID number
==== Notes ====
A trendline-specific ID number is returned by [[TL_New]] when the trendline is created.
==== Example ====
Assign a true/false value, indicating whether the trendline with an ID number of 3 is extended to the left, to ExtL variable:
<syntaxhighlight>Variable:ExtL(False);
ExtL=TL_GetExtLeft(3);</syntaxhighlight>
