Compiled script of Graphical Object not visible

deinit() is called when the script finishes,  and what does deinit() do in your script ?  yep,  deletes the Object . . .

ObjectDelete("Label_Obj_MACD");

I took out the deinit() section. Now I can see the 1-time result. In the Journal, I still see that the Object is removed as before though ...

Would you suggest to write a different deinit() section? I'm in the process of studying this ...

I'm making a similar exercise with Modifying Graphical Objects. But in this case, after canceling (graying out) the deinit section, the object does not appear on the chart? Why does it in the 1st case but not in this one? I attach file 'research_moveobjects.txt'.

Thanks so much. 

It looks like your Object is drawn at a price of 0.0 . . .  so is off sccren,  try drawing it at current price, i.e.  Bid

I changed the following line in section 6-7 of file 'research_moveobjects.txt':

   ObjectCreate("Obj_Reg_Ch",OBJ_REGRESSION,0,T1,Bid,T2,Ask);// Creation

With F1 I saw the prices location of ObjectCreate and changed 0 of t1 and t2 to Bid and Ask. 

However, still no line/object appears on the chart? 

Not sure what you are doing . . . I tried your code (with the Bid & Ask change) and it works fine . . .

The code . . .

It's working.
