Hi, there,

I want to open 2 trades everyday. Unfortunately the following code is not working. After the first 2 trades in the first day, the global variable "DayofTrade" keeps to be 0 instead of becoming back to -1. Could anyone here give me some help?

Many thanks in advance!

Inserted Code
int DayofTrade = -1;

int init(){return(0);}
int deinit(){return(0);}

int start()
{

   int MagicNumber=10;   
   if(Hour()==0 && DayofTrade == -1)
   { 
    OrderSend(Symbol(), OP_BUY, 1, Ask, 3, 0, 0,"my comment",MagicNumber);
    OrderSend(Symbol(), OP_SELL, 1, Bid, 3, 0, 0,"my comment",MagicNumber);
    DayofTrade=0;
   }   
   return(0);
}

You initialize DayOfTrade before the start() function. The code doesn't go all the way back to the beginning, it goes back to the start() function.

You need to move the initialization of that variable down to inside the start() function.

hey dogberry..... moving the int DayofTrade = -1; to the start function might have the unpleasant side effect of a new set of orders at every tick.....

perhaps you could use Day() or DayOfWeek() such as below......just a thought......h


Inserted Code
 
int DayofTrade = -1;
 
//+-----
int init()
  {
//----
 
//----
   return(0);
  }
//+-------
int deinit()
  {
//----
 
//----
   return(0);
  }
 
//+------------------------------------------------------------------+
int start()
  {
//----
   int MagicNumber=10;   
   if(Hour()==0 && DayofTrade != DayOfWeek())
   { 
    OrderSend(Symbol(), OP_BUY, 1, Ask, 3, 0, 0,"my comment",MagicNumber);
    OrderSend(Symbol(), OP_SELL, 1, Bid, 3, 0, 0,"my comment",MagicNumber);
    DayofTrade = DayOfWeek();
   }   
//----
   return(0);
  }
to trade and code, keep both simple... no call to impress....h

Many thanks Ronald. But exactly like hayseed said, moving the int DayofTrade = -1; to inside the start() function triggers a new set of orders at every tick.
