I have a problem when programming in MQL4. It is a very strange problem. I am curious whether someone can tell me what is going on here.
Below I present two pieces of simplified code, code version 1 and code version 2. Both versions are identical with the only difference the fact that in code version 1 one line is deactivated with a comment sign (//).
// code version 1
if(condition)
{
A=.... ; // calcuation of the value of A
Alert("A=",A);
B=.... ; // calcuation of the value of B
Alert("B=",B);
C=.... ; // calcuation of the value of C
Alert("C=",C);
// TicketNumber=OrderSend(..using A, B and C..);
Alert("TicketNumber=",TicketNumber);
}
// code version 2
if(condition)
{
A=.... ; // calcuation of the value of A
Alert("A=",A);
B=.... ; // calcuation of the value of B
Alert("B=",B);
C=.... ; // calcuation of the value of C
Alert("C=",C);
TicketNumber=OrderSend(..using A, B and C..);
Alert("TicketNumber=",TicketNumber);
}
When running the program with code version 1 then, when the condition is fulfilled, I see the results of A, B and C presented. The TicketNumber didn't get a new value. OK. When I do the same with code version 2, under the same circumstances, then the values of A, B and C are not presented, as if there are no alerts at all, but the order is sent.
My question: what is going on here, that with an activated OrderSend function the Alerts don't work anymore? The alerts are important to me because I use them to check the intermediate values of variables for checking the proper functioning of the program.
bool ticket=OrderSend(Symbol(),OP_BUY,Ask,3,0,0,"BuySellComment",MagicNumber,0,CLR_NONE); if (OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES)) Alert(OrderSymbol()," Ticket Number :",OrderTicket());
Hello, try this
switch(x) { case 'A': Print("CASE A"); break; case 'B': case 'C': Print("CASE B or C"); break; default: Print("NOT A, B or C"); break; }
