Hello to all professors

With this code, I get the last selling position

How do I change the code to get the first position?

//+------------------------------------------------------------------+
double FindLastSellPrice()
  {
   double oldorderopenprice=0;
   int oldticketnumber;
   double unused=0;
   int ticketnumber=0;
   for(int i=OrdersTotal()-1; i>=0; i--)
     {
      unused=OrderSelect(i,SELECT_BY_POS,MODE_TRADES);
      if(OrderSymbol()!="EURUSD" || OrderMagicNumber()!=Magic2) continue;
      if(OrderSymbol()=="EURUSD" && OrderMagicNumber()==Magic2 && OrderType()==OP_SELL)
        {
         oldticketnumber=OrderTicket();
         if(oldticketnumber>ticketnumber)
           {
            oldorderopenprice=OrderOpenPrice();

            ticketnumber=oldticketnumber;
           }
        }
     }
   return (oldorderopenprice);
  }

the last smallest "i" against the succeeding "i" that both "i" meets your intended condition above is the first sell position index
int first=0,last=0;
double firstprice=0.0,lastprice=0.0;
for...
{
  if(OrderSymbol()=="EURUSD" && OrderMagicNumber()==Magic2 && OrderType()==OP_SELL)
  {
    if (last==0)
    { 
      last = i; first = i;
        .
        .
        .
      lastprice = price(i);    
    }
    else 
    {
      if (i<first)
      {
        .
        .
        .
        first = i;
        firstprice = price(i);
      }
      continue;
    }
  }
  continue;
}
just typed
