help for creating object

New comment
 
Hello friends

I want to implement the FiboFan object on the chart with the help of standard MQL functions. But it seems I forgot something because nothing is displayed. Is it possible to guide me?

   FiboModifing("fiboH1", PERIOD_H1); // Filling structure elements by propper values. 

   bool cond =  ObjectFiboFan.Create(0, "fiboH1", 0, FiboStruct.Time1, FiboStruct.Price1, FiboStruct.Time2, FiboStruct.Price2);

   ObjectFiboFan.SetInteger(OBJPROP_COLOR, clrAliceBlue);


  }

I had forgotten to assign a value to the variables! I made the changes but the result did not change. Please help me to fix this problem

I found the answer. I was hoping someone could help me with that but..
Anyway, the answer for beginners like me who are looking for it is:
It seems that the codes written by the classes are removed from the chart at the end of the script, that's why the graphic object was not displayed. I entered the same codes in an indicator and the object was displayed!

Good you found a solution.

I would like to point you to this:


I suppose, you get your script working as well, if you use this function at the end.

Thank you for your participation in this matter. In fact, I had tried the function ChartRedraw()  before . The object was displayed for a few milliseconds and at the end the script was quickly removed from the chart.
