declare and initialize the trade request and result

[Essam Daoud]

Hi

Reading code examples in the Documentations, why there are times when this line is used for opening positions

MqlTradeRequest request={0};

but other times, this line is used for closing positions

MqlTradeRequest request;

Is this how to initialise the struct in mql5? but why leave out the "{0}" or put it in for both examples?

Thanks

Is this how to initialise the struct in mql5?

Per: https://www.mql5.com/en/docs/basis/variables/initialization

//--- initialization of all fields of the structure with zero values
MqlTradeRequest request={0};

but why leave out the "{0}" or put it in for both examples?

The documentation is rather voluminous and perhaps written by many people at different times.

MqlTradeRequest request={0};
MqlTradeRequest EmptyTradeRequest={0}

request.action = TRADE_ACTION_DEAL;
request = EmptyTradeRequest;

Just create an empty trade request and use it to clean ups.

Or, perhaps, you could try:

ZeroMemory(request);
