How to find highest and lowest open price orders?

New comment
 

for example-:

I have 3 buy orders and 4 sell orders open at the price below


3 Buy orders open price

2.5

2.3

2.6


4 Sell orders open price

1.6

1.2

1.1

1.5


Now I only want to display the highest of buy open price which is 2.6 and the lowest sell open price which is 1.1.

Anybody know how to do this?

 

Provided that your order magic number is stored in a variable myMagic, the code is as follows (havent tried compiling):


void printMyOrders() {
   int highestBuyPos=-1, lowestSellPos=-1;
   double highestBuyPrice=0.0, lowestSellPrice=1000000.0;

   for(int i=0; i < OrdersTotal(); i++){
      if(!OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
         return ;
      }
      
      if(OrderSymbol()==Symbol()) {
         if(OrderMagicNumber()==myMagic) {
            if(OrderType() == OP_BUY) {
               if(highestBuyPrice < OrderOpenPrice()) {
                  highestBuyPrice = OrderOpenPrice();
                  highestBuyPos = i;
               }
            }
            else if(OrderType() == OP_SELL) {
               if(lowestSellPrice > OrderOpenPrice()) {
                  lowestSellPrice = OrderOpenPrice();
                  lowestSellPos = i;
               }              
            }
         }
      }
   }

   if(!OrderSelect(highestBuyPos, SELECT_BY_POS, MODE_TRADES)) {
      Alert("Failed selecting highest buy order!");
   }
   else {
      OrderPrint();
   }

   if(!OrderSelect(lowestSellPos, SELECT_BY_POS, MODE_TRADES)) {
      Alert("Failed selecting lowest sell order!");
   }
   else {
      OrderPrint();
   }
}
 
Thank you very much
