regarding OrderTicket() function

I want my EA to check and make sure that it can only have one pending order in the pool at any one time, so I wrote the following code to do that:

int CheckOrders()

{

//----

int i,orders;

int tickets[];

//----

int ticket = 0;

int total = OrdersTotal();

//----

for(i=total;i>=0;i--) tickets = 0;

//----

for(i=total;i>=0;i--){

if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)){

if(OrderMagicNumber()==magic_base && OrderType()>1){

orders++;

tickets = OrderTicket();

Print("tickets = ",tickets);

}

}

}

Print("total = ",total," orders = ",orders);

while(orders>1){

for(i=total;i>=0;i--){

if(ticket==0 && tickets>0) ticket = tickets;

if(ticket>tickets) ticket = tickets;

}

if(OrderSelect(ticket,SELECT_BY_TICKET,MODE_TRADES)){

OrderDelete(ticket);

}

orders--;

}

Print("ticket = ",ticket);

//----

return(0);

}

It displays the number of pending orders in the pool by the same EA correctly, but it won't delete the unwanted pending orders, because it always shows that tickets = 0. and because of this, the OrderDelete(ticket) won't work. Could sb please tell me why this would happen?

 

Please check, getting error

Hello, I'm trying this EA but getting this error;

unknown subwindow number 1 for ObjectCreate function

and

name parameter for ObjectDelete function must be a string

What does that mean?

Thanks

MT4 Text indicator? How to...

if i want to draw text on the screen, must it be an object? is there an indicator style for me to draw simple #s on the screen?

 

Resources for MQL4 writing ?

Any videos I can buy, or a complete book on the subject. I have various tutorials, but none very helpfull. Sure would be nice to look at a real EA with notes next to each line indicating exactly what the line means.

Also helpfull if one could get a tutorial on editing an EA, I think that would be the best way to learn, editing an EA to fit your style.

Thanks for any info...
