Modifies the starting point location of a trendline with the specified ID number; returns a value of 0 if the starting point location was successfully modified, and 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_SetBegin_s (TL_ID, sDate, sTime_s, sPriceValue)</syntaxhighlight>
==== Parameters ====
[[TL_ID]] - a numerical expression specifying the trendline ID number
[[sDate]] - a numerical expression specifying the new starting point date; the date is indicated in the YYYMMdd format, where YYY is the number of years since 1900, MM is the month, and dd is the day of the month
[[sTime_s]] - a numerical expression specifying the new starting point time, including seconds; the time is indicated in the 24-hour HHmmss format, where 130000 = 1:00:00 PM
[[sPriceValue]] - a numerical expression specifying the new starting point price value (vertical position, corresponding to a value on the price scale of a chart)
==== Notes ====
A trendline-specific ID number is returned by [[TL_New_s]] when the trendline is created.
==== Example ====
<syntaxhighlight>Move the starting point of the trendline with an ID number of 3 to 10:00:00 AM on January 17th at a price value of 1365:
Value1=TL_SetBegin_s(3,1080117,100000,1365);</syntaxhighlight>
