Since only one version is supported, why not leave it alone in the KB, or at least make a redirect from the wrong version in big red letters?
The author can't do anything about versions in other languages.

I don't know why the number of lots obtained is 0.00 instead of 0.01?

If you need an account, I can provide it via private message.

OrderLots() also returns 0.

This is the correct behaviour. You have closed the position counter via CloseBy.

Run CustomReport - there will be more information to understand.

I manually closed all my positions using MT5, and the returned lot number was 0, which caused unexpected calculations for that order. Why does it return 0.00 instead of the official figure? For example, regarding the order count, I'm unsure whether to exclude this order. Logically, it shouldn't be excluded, but a return of 0 lots indicates an invalid order. 

Where can I modify this behavior?


 
If it's buy 0.01 and sell 0.03, will it return 0.02? I haven't tested it yet. I'll test it when I have time.

This is the correct behaviour, which is identical to the behaviour in MT4 in these situations. If two multidirectional 1 lot positions are closed via CloseBy, the total volume of the closed position should be 1, not 2.

The sum of lots is the trading volume, by which, among other things, the commission is calculated.

There will be an open position of 0.01 lot and two closed positions: 0.01 lot and 0.00 (information) lot.

If I want to count the number of trades, it should be 0.04, but now it is 0.03?

Gave all the links with details. Everything works correctly.
