It's just that the EA that creates objects should delete them when deinitialising.

What EA? I use standard (standard) drawing tools. And why delete objects? They should be stored in a bundle with a symbol and each time this symbol is loaded into the window, they should also be displayed. Each symbol has its own levels, trend lines, etc.

The objects are stored in conjunction with the chart, not the symbol. And on the chart window can be any symbols. That's why each symbol has its own chart. And if you compare, you can change symbols in the chart.

What's the point of binding drawing objects to a chart without linking them to a symbol? Well, it is as it is, what can be done. That's why I'm asking, maybe there are some tricks that cure it.
And so, MT and usability do not seem to know each other at all, programmers did for programmers :).

Friends, hello everyone )

Help, who knows. The Expert Advisor checks what orders are placed. And, periodically, when orders are executed or cancelled, i.e. OrdersTotal()=0, it still displays the property of the order, for example, type, symbol (probably the last in the history of orders). Is there a command, so that before rechecking the orders the Expert Advisor"clears the memory" so to speak, like ChartRedraw only for properties, data types? When the EA is restarted manually, there is no such problem for some time. Thanks in advance!

I haven't encountered this problem, as I keep my own records of orders, but I can assume that these are properties of the last selected order (last paragraph https://www.mql5.com/ru/docs/trading/orderselect ).

Before any check, the order must be selected, even if it is one in the terminal. And in order not to doubt the correctness of the received properties, you should check the closing time. If the closing time is greater than zero, then the order is closed or removed.

And from this text it is not clear whether the question is about MQL5 or 4

Hello.

I'm new to the MT4 platform. I've entered the correct username and password, and the available balance even appears, but the NEW ORDER button is inactive, even though I have a balance to trade; the same thing happens on smartphones.

Could someone help me by telling me how to solve this?

Thank you in advance.
