Trade Request Returns Invalid Request

[choongay]

Hi, can someone correct me what is the mistake below?

I got error code 10013 which mean invalid request.

FYI, I am using MetaQuotes-Demo account.

Thank you very much.

My code

bool Trade_Buy()
 {
   ZeroMemory(my_request);
   ZeroMemory(my_result);
   ZeroMemory(my_check_result);
  
   my_request.action       = TRADE_ACTION_PENDING;         // Setting a pending order
   my_request.magic        = magic_number;                         // ORDER_MAGIC
   my_request.symbol       = _Symbol;                                 // Symbol
   my_request.volume       = 1;                                           // Volume in 0.1 lots
   my_request.price        = 0.79;                                         // Price, reaching which the order must be executed
   my_request.stoplimit    = 0.89;                                        // Pending order is not placed if reach stop limit
   my_request.sl           = 0.86;                                           // Stop Loss
   my_request.tp           = 0.9;                                            // Take Profit
   my_request.type         = ORDER_TYPE_BUY;                    // order type
   my_request.type_filling = ORDER_FILLING_FOK;
   my_request.type_time    = ORDER_TIME_DAY;

   if(OrderCheck(my_request, my_check_result) == false)
   {
      Alert("ORDER_TYPE_BUY check failed\r\n");
      return false; 
   }
  if(OrderSend(my_request, my_result) == false)
   {
      Alert("ORDER_TYPE_BUY failed\r\n");
      return false;
   } // if the order is successfully accepted by the trade server, the OrderSend() function returns true.

   return true;
}

You are using TRADE_ACTION_PENDING and ORDER_TYPE_BUY, a BUY is not a pending. Check the documentation please.

Hello MQL5 Community.

I am getting this error when I ran my code in demo account. The error is "invalid request",. what is wrong with my code?

void GenerateTradeSignal(double ema5Buffer_0, double ema20Buffer_0, double ema5Buffer_1, double ema20Buffer_1)

      else

Any assistance will be appreciated. Thank you
