pair specificity?

[[Deleted]]

Good morning all....I have been battling with this dillemma for awhile now and need some assistance. I have a system that I run on my real account that uses two EA's: one to place the trades once the conditions for trading have been met, and one that removes orders once my trades have closed for profit. I have a second system(that trades on totally different parameters) and I want to automate it as well. Here is my problem: the second system needs to be pair specific. I am not good at coding so right now, I basically assess accountbalance to decide whether or not to remove orders. If someone can help me by giving me a snippet of code that would look back at closed orders and search for an ordermagicnumber, then I can close an order using a different magic number. This would allow me to assign different magic numbers to the various pairs I trade and therefore be able to delete the exact right order once the first one has closed!

Any help would be greatly appreciated! Thank you.....

- use magic number to distinguish between distinct strategies
- use OrderSymbol() to distinguish between currencies.

This is pseudo-code. Check for correct syntax
// code for order placement
int MAGIC_EA1=1000;

// check here for trade placement wih STRATEGY EA1
OrderSend(Symbol(), MAGIC_EA1, ....);  // Symbol() will be eurusd if EA attached to an EURUSD chart, it will be EURJPY if...., and so  on.


// check here for trade placement wih STRATEGY EA2
OrderSend(Symbol(), MAGIC_EA2, ....);  // Symbol() will be eurusd if EA attached to an EURUSD chart, it will be EURJPY if...., and so  on.






/// code for order close
for(int i=OrdersTotal()-1; i>=0; i--)
{
   if( !OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
       continue;
   if(OrderMagicNumber()==MAGIC_EA1)
   {
      // check close for trades with magic number MAGIC_EA1
   }  
   if(StringLowerCase(OrderSymbol())=="eurusd")   // check if in your broker it isn't "EURUSDm"
   {
      // check closing conditions for eurusd
   }
   if(StringLowerCase(OrderSymbol())=="eurjpy")      {
      // check closing conditions for eurjpy
   }

}

string StringLowerCase(string str)
  {
   string s = str;
   int lenght = StringLen(str) - 1, symbol;
   while(lenght >= 0)
     {
       symbol = StringGetChar(s, lenght);
       if((symbol > 64 && symbol < 91) || (symbol > 191 && symbol < 224))
           s = StringSetChar(s, lenght, symbol + 32);
       else 
           if(symbol > -65 && symbol < -32)
               s = StringSetChar(s, lenght, symbol + 288);
       lenght--;
     }
   return(s);
