Invalid Expiration OrderSend expert

[tinivini]

Hi .

I'm beginner in MQL5. I am trying to create OrderSend expert.

I write this code :

int OnInit()
{
    MqlTradeRequest request ;
    MqlTradeResult result ;

    request.action = TRADE_ACTION_PENDING;
    request.type = ORDER_TYPE_BUY_LIMIT;
    request.symbol = _Symbol;
    request.volume = 100 ;

    request.price = 45400  ;
    request.sl = request.price - (request.price*0.1);
    request.tp = request.price + (request.price*0.2);
    request.expiration = D'2021.10.10 13:00:00';
    request.type_filling = ORDER_FILLING_RETURN ;

    OrderSend(request,result);

    return(INIT_SUCCEEDED);
} 

But when run I am getting this expert error :

" 2021.10.01 00:00:00   failed buy limit 100 [my symbol] at 45400 sl: 40860 tp: 54480 [Invalid expiration]"

In Strategy Tester window I enter custom period from 2021.10.01 to 2021.10.20. I also tried my hard and select different date but not worked anything.

Any advise will be appreciated!

You have to check whether the Symbol allows such orders - look into the specification:
