TL SetBegin

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

TL_SetBegin (TL_ID, sDate, sTime, sPriceValue)

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 - a numerical expression specifying the new starting point time; the time is indicated in the 24-hour HHmm format, where 1300 = 1:00 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 when the trendline is created.

Example

Move the starting point of the trendline with an ID number of 3 to 10:00 AM on January 17th at a price value of 1365:

Value1=TL_SetBegin(3,1080117,1000,1365);
