# RectangleSetBegin

From MultiCharts

Modifies the starting point location of a rectangle 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 rectangle ID number is invalid.

Of the two end points of a rectangle, the point with the earlier date and time is always considered to be the starting point; if the rectangle is vertical, the point with the lower price value is considered to be the starting point.

## Usage

`RectangleSetBegin (ID, sDate, sTime, sPriceValue)`

**Parameters***ID*- a numerical expression specifying the rectangle 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 rectangle-specific ID number is returned by RectangleNew when the rectangle is created.

## Example

Move the starting point of the rectangle with an ID number of 1 to 10:00 AM on January 17th at a price value of 1365:

`Value1=RectangleSetBegin(1,1080117,1000,1365);`
