Declaration of a variable request of type MqlTradeRequest, and all elements of the structure initialized to 0.

it's important ?

it's possible do not incluse to the code ?

i thinks it's for have not error and not conflit ? 

My program work :

   //buy
   MqlTradeRequest request={0};
   request.action=TRADE_ACTION_DEAL;
   request.magic=1234;            
   request.symbol=_Symbol;               
   request.volume=0.1;                        
   request.sl=0;                                
   request.tp=0;                              
   request.type=ORDER_TYPE_BUY;              
   //request.price=GetRandomPrice(request.type);  // open price
   MqlTradeResult result={0};
   OrderSend(request,result);

 Just structure price (open price) i d'ont understand, it's not important ?

It depends on the symbol execution type  ( ENUM_SYMBOL_TRADE_EXECUTION ) if it's Market or Exchange execution the you don't send the open price,  if it's Request or Instant execution then you need to send the open price.

There is a little more info in this thread:  https://www.mql5.com/en/forum/11303
