Newbie need help

[Kiril Spiridonov]

Hello! I really need help with my EA.

I show great results on backtesting, but unfortunately, I cannot publish it, because of errors.

I am not a professional programmer and I really need help.

I've copied and pasted some part of the help and I think it helped to solve some errors.

I get error 130 and 4051 and sometimes error 1

Just, at a glance, it seems you are using a lot of undeclared variables.  Like int orderticket;

I think you mean here, you want to select by orderticket. If that's the case, maybe you want to use this to get order ticket:

int tradeticket;
for(int i=0;i<OrdersTotal();i++)
{
   if(!OrderSelect(i,SELECT_BY_POS))
       continue;
   tradeticket=OrderTicket();
}

Just like Ian said, check all your variables.
