TL_SetExtRight (Reserved Word)
DisclaimerTrendlines can be extended to the left or right. This reserved word enables you to toggle the trendline between extended to the right and not extended.
Value1 = TL_SetExtRight(Tl_ID, Extend)
Tl_ID is a numeric expression representing the ID number of the trendline, and Extend is a true/false expression that either extends the trendline to the right or not.
Value1 is any numeric variable or array. You must assign the trendline reserved word to a numeric variable or array so that you can determine whether or not the reserved word performed its operation successfully.
Remarks
When the reserved word performs its operation successfully, a 0 is returned. When a reserved word cannot perform its operation, it returns an error code. For a list of error codes, see EasyLanguage Drawing Object Error Codes.
It is important to remember that if an invalid ID number is used, the reserved word will return a value of -2 and no additional operations will be performed on any trendlines by the trading strategy, analysis technique, or function that generated the error.
Example
The following turns on the extend right status of the trendline referenced by Value99 (that is, the trendline will extend right):
Value1 = TL_SetExtRight(Value99, True);
Additional Example
The following statements draw a trendline at the low of a key reversal bar and extend it to the left and right:
Variable: ID(-1);
If Low < Low[1] AND Close > High[1] Then Begin
ID = TL_New(Date[1], Time[1], Low, Date, Time, Low);
Value1 = TL_SetExtRight(ID, True);
Value2 = TL_SetExtLeft(ID, True);
End;
