How do you need a lot for trailing stoploss?

Oh, so I meant making changes to the existing code of your program. It turns out that your program is built using the"MQL5 Wizard" application. I can't help you here, because I've never played with this builder, and I'm not familiar with its program structure.

A lot is needed in money management

Please advise how to close position (e.g. buy EURUSD 0.7 lot)? Through OrderSend() with opposite type of sell and volume 0.7 or is there a better option?

[Yedelkin]

WindSW: Please, advise how to close position (e.g. buy EURUSD 0.7 lot). Is it via OrderSend() with the opposite type of sell and volume 0.7 or are there more correct variants?

Yes, opposite orders with a total volume equal to the volume of the position to be closed.

There is also CTrade trade class from the Standard Library. There is a position closing method there. But the principle is the same.

What should OrderSend() look like? More precisely, what parameters should be entered in the request, the same as when opening a position, except for sl and tp?

Not at all, I've seen it, but it doesn't say anything about the composition of the request when closing. It lists all the options except closing. That's why I'm asking.

There are mandatory fields for each type of trade request. They must be filled in. "Opening a position" or "Closing a position" are just the result of a specific trade request, the rules for filling them are the same. I.e. take your working variant of the "open" request and change the order type. Fill in the unnecessary mandatory fields with zeros.
