Returns the price value (vertical position, corresponding to a value on the price scale of a chart) of the starting point of a trendline with the specified ID number; returns a value of -2 if the specified trendline ID number is invalid.
Of the two end points of a trendline, the point with the earlier date and time is always considered to be the starting point; if the trendline is vertical, the point with the lower price value is considered to be the starting point.
==== Usage ====
<syntaxhighlight>TL_GetBeginVal(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 value, indicating the price value of the starting point of a trendline with the ID number of 3, to Value1 variable:
<syntaxhighlight>Value1=TL_GetBeginVal(3);</syntaxhighlight>
