Can you tell me why, when testing in "viewer-less" mode, the line
generates error 4203
but not in visual mode.

Hello, could you please advise me if it is possible to implement real trading on mt5? I trade at alpari, I have seen the article about copying trades in mt4, everything seems to be clear. My question is the quotes. My using Mt5 will only work in demo mode, there are not many quotes, and only few of them are available. Is it possible to set up MT5 to read MT4 quotes and will this method be acceptable for real trading or will it be a crutch that will not work? Thanks in advance for your reply.
Crutches whose reliability and effectiveness is highly questionable.
IMHO.
because graphical objects are not supported in "visionless" mode
So before each use of functions for graphical objects you have to check if the visual is running...
Doesn't seem right to me. And what is the error about identifier? It would be more appropriate ERR_OBJECT_ERROR.
Why does it allow to create objects but not to modify properties?)

In the tester, graph objects are not supported at all (at least for now), neither in visual nor in non-visual mode.
No, you just need to write separate code for tester and for realtime, or better to do everything through calculations, and graphics already output by ready calculations, then it can be disabled by one flag if work in tester.
I also use a flag to disable some prints that are directly used in debugging. By the way, here's a question:
Is it quicker to check the status of a flag than to call Print()? That is, does it make sense to disable printers during optimization?
