svds75:
No, I need to set it manually and check it programmatically.

Then I have to read the visibility flag and do a logical & with the constant.

[Dmitry Fedoseev]

Like this:

   long cf=ObjectGetInteger(0,"name",OBJPROP_TIMEFRAMES);
   Alert(((cf&OBJ_PERIOD_H1)==OBJ_PERIOD_H1) || cf==0);

If the visibility flag on H1 is set, it will be true.

Integer:
Then you have to read the visibility flag and do a logical & with the constant.

If you mean:

ObjectGetInteger(0,"line",OBJPROP_TIMEFRAMES,OBJ_PERIOD_W1&OBJ_PERIOD_MN1,res);

Or

ObjectGetInteger(0,"line",OBJPROP_TIMEFRAMES,OBJ_PERIOD_W1&&OBJ_PERIOD_MN1,res);

Same thing.

No. There's no need to do get with enumeration. Just get, and then check if the required timeframe flag is set. Above is an example.

Your mistake here is bool(res), since res is always greater than 1 in any mapping, see what is returned in res, thus bool(res) will only return 0 or false when res=0

You are using type conversion and comparison inattentively

There you go:

If the visibility flag on H1 is set, it will be true.

It's working, thank you.

meat:

As a continuation of my previous post, I managed to find the problem area causing the bug using the scientific method.

We have a library with this function:

Here is the main file:

The resulting Expert Advisor does not work and displays in the log: "EX5 loading failed".

Thanks for the post, it was fixed.

Hi. I locked the EA in OnInit function and it must be the reason why the terminal hangs when I turn off the EA and change timeframe (timeframe does not change after the brakes). So my question is: Is it caused by hangs? If so, is it corrected if I move the algorithm to OnTick? If no, what would help?

PS: The loop has a function Sleep, so that the terminal is not overloaded. The input fields are read in the loop.

OnInit - serves only for initialization. All calculations must be done further - OnTick, OnTimer etc.

If you need to know the change in the input field, there is a standard library for that: https://www.mql5.com/ru/docs/standardlibrary/controls/cedit
