And without "if"? ...

There's no such thing as an "if". )))

Hello, I can't understand why the stops aren't showing?

input int         TakeProfit=999;   // Take Profit
input int         EA_Magic=12345;   // Magic Number советника

int OnInit()
  {

Top2n: Hello, I can't understand why no stops are being placed?

Firstly, initialisation is required:

MqlTradeRequest mrequest={0};   // Будет использоваться для отсылки торговых запросов
MqlTradeResult  mresult={0};    // Будет использоваться для получения результатов выполнения торговых запросов

Secondly, the ability to place sl and tp depends on the market order execution mode set by the broker. Look up how many of these modes there are in the Handbook and check which mode is set by the broker.

I have zeroed out via ZeroMemory(mrequest);

I don't really understand about the order execution modes, alpari broker, i think everything is standard. Damn nonsense, doesn't want to and that's it. I have already tried to use sl and tp, it shows the current price + sl. I guess it is Ok!

Do you have any messages in the log?

[Yedelkin]

Top2n I don't really understand the order execution modes, I am an alpari broker, I think it is all standard. I do not know what to do with this kind of forex broker, I still do not know what to do with this kind of forex. I do not know what to do if I try to go back to the comment sl and tp?

I don't follow Alpari, but I think all the issues with not setting the levels you mentioned were related to Alpari. Try placing your order on the MQ demo account and you will be fine.

About order execution modes. You are using the https://www.mql5.com/ru/docs/trading/ordersend function. Please read carefully this section of the Guide: https://www.mql5.com/ru/docs/constants/structures/mqltraderequest and answer the question for yourself: "how many execution modes are available for market orders". If you can't answer this question, please ask.

tol64: Are there any messages in the log?

The developers have not yet provided a possibility to reflect in the log messages about the inability to set sl and tp levels in Market Execution and Exchange Execution modes. And there is no reason to do it. The programmer should determine the mode set by the broker.

Anyway, not to guess, you should analyze all the errors and return codes. It is easier and faster to analyze what to do next. ))

[Yedelkin]

tol64: You still need to analyse all the errors and return codes to avoid guesswork. It's easier and quicker to figure out what to do next. ))

...Especially when you know that "errors and return codes" are simply not provided in this particular case :) No doubt, the question itself is correct, but in this particular case, it won't help :/
