发送短订单，MQL5

Question

所以我对用MQl5编程非常陌生，我有一个关于发送订单的问题。这是MqlTradeRequest

double TakeProfitOpenS, StoplossLine1S, StoplossLine2S;
   if(BreakoutShort) {TakeProfitOpenS=open; StoplossLine1S=(close-open)*2+close; StoplossLine2S=(close-open)*1.8+close;}
   else {TakeProfitOpenS=0; StoplossLine1S=0; StoplossLine2S=0;}
   
   //---    Defining the BounceShort 
   double BounceShort = StoplossLine1S <= close <= StoplossLine2S;   

   //---    Stoploss for short 
   double   slShort     =     Bid      >= (2.5*GCdif_EMA)+close;
   double   slShort1    =     close    > StoplossLine1S;
   
   //---    Take Profit for short 
   double   tpShort     =     TakeProfitOpenS;
   
   MqlTradeRequest request={};
      request.price        =     SymbolInfoDouble(_Symbol,SYMBOL_BID);   // Short
      request.magic        =     EXPERT_MAGIC;                 // EA magic number so you can track trades 
      request.action       =     TRADE_ACTION_DEAL;            // Market order
      request.symbol       =     _Symbol;                     // Symbol 
      request.type         =     ORDER_TYPE_SELL;              // Long
//---    request.order        =     "OrderTicketSell";            // The orderticket so you can trace the individual trade 
      request.deviation    =     5;                            // Maximum price deviation 
      request.volume       =     0.25;                         // This should be €25.000 
      request.tp           =     tpShort;                      // Take profit Short 
      request.sl           =     (slShort || slShort1);        // Stoploss Short
      request.comment      =     "Sell using OrderSendAsync()";
   MqlTradeResult result={};
   if(!OrderSendAsync(request,result))
     {
      Print(__FUNCTION__,": error ", GetLastError(),", retcode = ", result.retcode);
     }

如果发生这种情况：

   double BreakoutS  =  BreakoutShort && GCRB < 200;  

我想开这个行业，但我不知道从哪里开始。如果有人能告诉我怎样才能用这个来发送订单，那就太棒了！提前谢谢。

Answer 1

我用自定义函数来执行买卖，

buy();
sell();

默认情况下，这些代码将执行0.01批次，但您可以执行如下所示，

buy(0.04);
sell(0.08); 

任何你想要的东西，
