Creates an object with the specified name, type, and the initial coordinates in the specified chart subwindow

Parameters

sub_window	Number of the chart subwindow. 0 means the main chart window. The specified subwindow must exist (window index must be greater or equal to 0 and less than WindowsTotal()), otherwise the function returns false
time1	The time coordinate of the first anchor point
price1	The price coordinate of the first anchor point
time2	The time coordinate of the second anchor point
price2	The price coordinate of the second anchor point
time3	The time coordinate of the third anchor point
price3	The price coordinate of the third anchor point

Returns

Returns true or false depending on whether the object is created or not. To read more about the error call GetLastError().
If the object has been created already, the function tries to change its coordinates.
