last deal properties

so the problem is that my EA doesn't work even though there are no errors, if anyone knows what I did wrong and instructs or corrects me, I would be grateful.

#include <Trade/Trade.mqh>

      myrequest.type_filling = ORDER_FILLING_IOC;
      myrequest.price = SymbolInfoDouble(_Symbol,SYMBOL_ASK);
      myrequest.tp = myrequest.price + 1;
      myrequest.sl = myrequest.price - 0.5;
      myrequest.deviation= 50;
