ObjectGetTimeByValue Triangle Bug ?

New comment

Hello,

I try to get Time for Object Triangle, but it seem2 any bug.

I use ObjectGetTimeByValue to get time value.

It works for Rectangle and Trend Line, but NOR for Triangle.

Any something wrong ?

Or any another way to get the time of the Triangle ?

Regads

below my code.

      string objname4="TRIANGLE";
      double v4 = ObjectGetDouble(0,objname4,OBJPROP_PRICE1,0);
      datetime T4 = ObjectGetTimeByValue(0,objname4,v4,0);
      
      string objname5="TRENDLINE";
      double v5 = ObjectGetDouble(0,objname5,OBJPROP_PRICE1,0);
      datetime T5 = ObjectGetTimeByValue(0,objname5,v5,0);
      
      string objname6="RECTANGLE";
      double v6 = ObjectGetDouble(0,objname6,OBJPROP_PRICE1,0);
      datetime T6 = ObjectGetTimeByValue(0,objname6,v6,0);

but the result like image below

hello..,

This is not about create Triangle .

but, how to get TIME value of Triangle on chart use ObjectGetTimeByValue

ObjectGetTimeByValue

Oh i'm sorry my bad i wasn't paying attention.

An object can have several values in one price coordinate, therefore it is necessary to specify the line number.

This function applies only to the following objects:

Trendline (OBJ_TREND)
Trendline by angle (OBJ_TRENDBYANGLE)
Gann line (OBJ_GANNLINE)
Equidistant channel (OBJ_CHANNEL) - 2 lines
Linear regression channel (OBJ_REGRESSION) - 3 lines
Standard deviation channel (OBJ_STDDEVCHANNEL) - 3 lines
Arrowed line (OBJ_ARROWED_LINE)

trendline value Questions from Beginners MQL5 problem with value of

thanks,

I had tried and same result.

in the Points above, there is no "Rectangle"

But I use the function to get TIME Value of Rectangle and correct result.

pls see my screenshot above.

It means you can not use that function on a rectangle.

But i think you can roll your own by using trendlines and that should work.

I use the function for Rectangle, and got correct value

see my image at the beginning post
