Sorry, I can't compile a simple-simple line. 
double price=(Ask+Bid)/2;
Before I put it in, it compiled to 0. Now...

Thank you!

I can't get the cycle right, on every tick a couple of orders are opened, it should be like this. When a tick comes, variable X is declared inside the loop, accordingly taking value 0.

Then X=number of orders is calculated within the loop, and if X=0 or 1, then they open.

You have declared a variable but not zeroed it. Therefore, with every tick it will only grow !!!!!!

That's not the right way to do it. 

double price=(Ask+Bid)/2;
Thank you!!! I'll reset it now. But all the same, something is wrong, maybe the first loop for some reason does not work and X always remains 0. I cannot even find this out for sure, because Alert ("X",X) does not log anything, only orders with zeros are logged.
VOLDEMAR:

That's not right.


You are mistaken here. With every tick this variable is declared anew, hence it equals 0.

It takes it out of hand

int start()
  { int X; double price=(Ask+Bid)/2;      
//----
       for(int Uy=OrdersTotal();Uy==0;Uy--){Alert ("OrdersTotal()",OrdersTotal());
OrderSelect( Uy,SELECT_BY_POS );Alert ("Uy",Uy);if(OrderSymbol()==Symbol()&&(OrderMagicNumber( )==1000||OrderMagicNumber( )==2000 )&&OrderSymbol()==Symbol())
{X ++;}  Alert ("X",X);}
//----
if (X<2){
   tiket= OrderSend( Symbol(), OP_BUYSTOP,  volume*A, price +otstup*Point, 3, R1, price+takeprofit*Point+otstup*Point, "OP_BUYSTOP", 1000,  expiration, Red); 
   Alert ("OP_BUYSTOP", GetLastError( )); 
   RefreshRates();
   tikett= OrderSend( Symbol(), OP_SELLSTOP,  volume*A, price -otstup*Point,  3,R2, price-takeprofit*Point-otstup*Point, "OP_SELLSTOP" , 2000,  expiration,C'0,128,255' );
    Alert ("OP_SELLSTOP", GetLastError( )); 
    }       
   
//----
   return(0);
  }
Roger:

This is where you are wrong. With every tick this variable is declared anew, so it equals 0.

Yes, if you set it as x=0, it is zeroed if you just set it as x:, it is not zeroed, it is incremented.

VOLDEMAR:

Yes, if you set it as x=0, it will go to zero if you just set it as x:, it won't go to zero, it will go up.



Where in the annals did you read that?
