Someone had the experience to try to move object and it not obey and return success?

The follow expert do not move the lines... how to report a bug to metaquotes? HLineCreate and HLineMove has been based on the documentation page of OBJ_HLINE. Metatrader version is from april 4 2023.

My program doesn't work. I think system facility X is broken.

It is almost always your code.

   datetime today = iTime(ativo, PERIOD_D1, 0);
   int pbars = iBarShift(ativo, PERIOD_CURRENT, today) + 0;
   double hp = iHigh(ativo, PERIOD_CURRENT, pbars);
   double lp = iLow(ativo, PERIOD_CURRENT, pbars);
   double mi = (hp + lp)/2.0;

You are moving the lines to the H/L/mid of the first bar (current timeframe) of the day. They will never move after that.

Perhaps you meant the highest high/the lowest low of the day; which you can get from the D1 bar zero H/L.

On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

On MT5: Unless the current chart is that specific pair/TF, you must synchronize the terminal Data from the Server before accessing candle/indicator values.

Why are you using OnTimer? Nothing has changed, nothing needs to update until a new tick arrives.

William, i have tried this code before and it move the lines to the open of the bar on OnInit as expected, and after it I expected it will move to the high, low and middle point of the bar. The problem is that the three objects stay on the open of the bar. Do you have a suggest to fix?

Also, I tested changing pbars to zero and it do nothing after the OnInit code.

I saw right now when I was reviewing the code that I had a typo on the name of the objects on OnTimer, it is missing a T . Thank you.
