MQL4 to MQL5

[johnnybegoode77]

How do I rewrite these from mql4 to mql5?

1) asking1 = MarketInfo("GBPUSD",MODE_ASK);

2) int ticket=OrderSend("EURUSD",OP_BUY,Lots,Ask,3,0,0,"My EA",12345,0,Green);

//********************************************  Emulation *******************************************

//--- Declaration of constants
#define OP_BUY 0           //Buy

Still get

Error: 'OrderSend' - wrong parameters count  

for

int ticket=OrderSend("EURUSD",OP_BUY,Lots,Ask,3,0,0,"My EA",12345,0,Green);

What did I missed in the Emulation?

There's an example of opening a random pending order using OrderSend(), as you see the structure of 'mql5 OrderSend()' is not the same as 'mql4 OrderSend()'

//+------------------------------------------------------------------+ 
//| Sets a pending order in a random way                             | 
//+------------------------------------------------------------------+ 
uint SendRandomPendingOrder(long const magic_number) 
  { 
//--- prepare a request 
   MqlTradeRequest request={0}; 
   request.action=TRADE_ACTION_PENDING;         // setting a pending order 
   request.magic=magic_number;                  // ORDER_MAGIC 
   request.symbol=_Symbol;                      // symbol 
   request.volume=0.1;                          // volume in 0.1 lots 
   request.sl=0;                                // Stop Loss is not specified 
   request.tp=0;                                // Take Profit is not specified      
//--- form the order type 
   request.type=GetRandomType();                // order type 
//--- form the price for the pending order 
   request.price=GetRandomPrice(request.type);  // open price 
//--- send a trade request 
   MqlTradeResult result={0}; 
   OrderSend(request,result); 
//--- write the server reply to log   
   Print(__FUNCTION__,":",result.comment); 
   if(result.retcode==10016) Print(result.bid,result.ask,result.price); 
//--- return code of the trade server reply 
   return result.retcode; 
  }

Do you have a universal emulation scripts?

(Those that could cut and paste?)

Thank you!
