Error when opening an order:
4756 : Failed to send trade request
Which appears unpredictably at all, is this analogous to re-quotes in MT4 ?

A requote is a response from the server, and here it failed to send a trade request to the server for some reason. Probably - I don't know exactly.

most likely a requote, no other errors when opening an order, the error is exactly when opening a market order, reproduced once out of 5-10 attempts, here is the terminal log looked at:

OK a requote is a requote..., how do I detect requotes in MT5?
error 4756 : Failed to send trade request
Not good, what is the best way to detect a requote? I don't want to send 10 requests to the server if I get 4756, MT4 usually try to avoid requotes, but MT5 is cooler ;)
i read the search results on the forum, but as far as i understood there is no more efficient way to deal with requotes than sending a couple dozens of trade requests to the server.

Is (deviation: 30) not too little?

On EURUSD it is even by a large margin not on the news market.

It depends on which broker. Even the best ones are prone to artificial slippages. And 3 points in a case like this is nothing...

Missed the n-twenty years.
Breakeven formula:
breakeven = sum(Pi*Li)/sum(Li). Where Piis the opening price of a trade, Li is the lot of that trade
So we get the following formula
Ask+Pip=(sum(Pi*Li)+Ask*X)/(sum(Li)+X)
And using mathematics we come to the lot
X=(sum(Pi*Li)-sum(Li)*(Ask+Pip))/Pip
Please give me a hint, I'm having some kind of problem. I have to calculate a lot for a deal opened at current price so that the breakeven point of all deals was in Pip points of the current Ask price. All trades are unidirectional, let it be buy.

It's up to you, of course, but PI (Pi, pI, pi) is still a bit different )))
