How to select by pos and compare 2 orders at a time? How to make a OrderSelect loop?

 

You need to decide what you want to compare.

You can only select one order at a time using orderselect().

Save the value you want to compare in a Variable.

Compare the Next value with the one you have saved. 

Thanks
I know what I want to compare, 

 (1st with 2nd) orders, (3rd with 4th), (5th with 6th), (7th with 8th), (9th with 10th) ....till i, TotalOrder 

Yes selecting one order at a time, but loop it. To select 1 and 2, compare, select 3 and 4 then compare .... until total order

It would look something like this.

for(int a=OrdersTotal()-1;a>=0;a--){
   if(OrderSelect(a,SELECT_BY_POS,MODE_TRADES)==true){
      if(1st_Compare_Whatever != 0){
         2nd_Compare_Whatever=Value_You_Want_Compared;
         if(1st_Compare_Whatever > 2nd_Compare_Whatever){
            What_Ever_Count++;
            1st_Compare_Whatever=0;
            2nd_Compare_Whatever=0; 
            Continue;
         }
      }
      1st_Compare_Whatever=Value_You_Want_Compared;
   }
}

for (int i = 0; i < OrdersTotal(); i += 2) 

thanks
  nice that is a good idea, but how do I combine and compare them? Could I place selected order in a variable? 

for (int i=OrdersTotal()-1;i>=0; i--) {  

        for (int i = 0; i < OrdersTotal(); i++){

        (OrderSelect(i, SELECT_BY_POS)) = var A



                 for (int i = 0; i < OrdersTotal(); i += 2) {

                 (OrderSelect(i, SELECT_BY_POS)) = var B

ex.  

             if (OrderOpenPrice() of var A + OrderOpenPrice() of var B) > 5

            {

                           then OrderClose both order 1 and 2

}

then what about, 3 and 4, 

5 and 6,

7 and 8 ... 

after selecting an order save the value: some_ticket = OrderTicket(); Then refer to your orders only by their ticket numbers. Use OrderSelect(some_ticket, SELECT_BY_TICKET); to quickly select an order before doing any operations on it. Trying to rely on which order is currently selected through some levels of nested loops and function calls is a sure way to get into trouble and make your head hurting while trying to understand what might be going on when something is wrong in your reasoning once the code gets more complicated.

Make it simple and robust by referring to orders only via their ticket number.

first let me understand what u what compare the OrderOpenPrice or the symbol or TP or what?

& B.T.W with this code:

for (int i=OrdersTotal()-1;i>=0; i--) {

u r selecting the last order

for (int i = 0; i < OrdersTotal(); i++){

  (OrderSelect(i, SELECT_BY_TICKET)) = int ticket A



for (int i = 0; i < OrdersTotal(); i += 2) {

  (OrderSelect(i, SELECT_BY_TICKET)) = int ticket B

ex.

if (OrderOpenPrice() of int ticket A + OrderOpenPrice() of int ticket B) > 5

{

then OrderClose both ticket A and ticket B

}
