Returns the price value (vertical position, corresponding to a value on the price scale of a chart), at which an arrow object with the specified ID number has been placed.
Arw_GetVal returns a value of -2 if the specified object ID number is invalid.
Usage
Arw_GetVal(ObjectID)
Where:
- ObjectID - a numerical expression specifying the object ID number.
Notes
- An object-specific ID number is assigned by Arw_New, Arw_New_s, Arw_New_self or Arw_New_self_s when the arrow object is created.
- Use Arw_GetActive, Arw_GetFirst or Arw_GetNext to get the object-specific ID number of an already created arrow.
Example
Assign a value, indicating the price value at which an arow object with the ID number of 3 has been placed, to the Value1 variable:
Value1 = Arw_GetVal(3);
