Please advise why adding the string #property strict prevents arrows from being drawn, here is all the code

To the seller of this indicator.

Thank you...

Can anyone tell me what to do if during an EA test it refuses to copy buffers?

Identify the cause.

[Roman Sharanov]

Artyom Trishkin:

Identify the cause.

And what might it be? Is it the size of the code? I purposely disabled all logic, left only buffer copying and nothing

Everyone's telepathic at the weekend...

An out of memory error pops up when running a test (won't start). How to fix it?

After restarting the terminal, the test starts and then after a few tests it is out of memory again.

The program you are testing eats up all your memory. Look for errors in it. Check the "Journal" and "Expert Advisors" logs on the demo (not in the tester) - what does it say there? Perhaps, it says something about memory leakage during the timeframe change.

I will not guess further without the code.

There are a lot of undeleted objects in logs after testing is over. Several thousand... Is that a problem?

There's a pile of unsuccessful objects in the logs after testing ends. Several thousand... Is that the problem?

This is where they'll be able to answer for sure.
