TL_SetBegin_s (TL_ID, sDate, sTime_s, sPriceValue)

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)

A trendline-specific ID number is returned by TL_New_s when the trendline is created.
Example
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);
