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.
TL_GetBeginVal 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
TL_GetBeginVal(TL_ID)
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.
- Use TL_GetEndVal to get the end value for a specified trendline.
Example
Assign a value, indicating the price value of the starting point of a trendline with the ID number of 3, to the Value1 variable:
Value1 = TL_GetBeginVal(3);
