TRADE_ACTION_DEAL	Place a trade order for an immediate execution with the specified parameters (market order)

Vladimir, can't you write it in Russian?

You can't. Because I quoted the full reference. Otherwise, it's a long shot: everyone has a 'ticket' and some have 'tickets'. That's why the functions, help and quotes from the help are in English.

And they have "tickets" just because they start translating with google :)

In the Russian official help, there are "tickets".

Hello all! I think the question is primarily for the pros (as it turns out). It has been a week with one question about the code.

For example - we know that the M5 candle contains 5 candles M1 (for example, 00:00, 00:01, 00:02, 00:03 and 00:04). Further we will consider only this conjunction - i.e. we run the indicator on M1 and want to see the indicator readings from M5.

I.e. to correctly display data of the middle TF on the lower one, I should loop through all 5 bars of the lower TF as they appear. I.e. the first bar appears 00:00, then 00:01 etc. up to 00:04 and after that the next one appears. It means the cycle should be from 0 to 4 - this is the maximum, while gaps in history are not considered. The problem is that I get the cycle from 0 to 5, and I do not have enough logic to make it up to 4! Believe me, I've been struggling with this for a week now and I'm really asking for your help. Below is a very truncated code where the loop goes to 5 instead of 4. I want it to 4!!!!!

How do I add a list view editing window?

https://www.mql5.com/en/docs/standardlibrary/controls/clistview

I have the library above. I want to add an edit box with a label inside this list. Can you tell me how I can do this? I've tried, but it doesn't work.

OK, I confess: caught me. Answered quickly and didn't switch the help language 😎

[Roman Sharanov]

The question is this. Can I open 2 (or more) charts at the touch of a button so that they are positioned vertically, equally occupying the entire monitor?
