SortedByValue

como na linguagem python

sorted(key_value.items(), key = lambda kv:(kv[1], kv[0]))

1. As ordens do Grid EA são classificadas de acordo com o preço de abertura

void SortedByOpenPride()
  {
   long    OrderTicketBuffer[];
   double  OpenPriceBuffer[];

   for(int i = PositionsTotal()-1; i>=0; i--)
     {
      if(m_position.SelectByIndex(i))
        {
         OrderTicketBuffer[i] = long(m_position.Ticket());
         OpenPriceBuffer[i] = m_position.PriceOpen();
        }
     }

   SortedByDouble(OrderTicketBuffer,OpenPriceBuffer);
  }

   string    key[5];
   double    value[5];

   key[0] = "USD";
   key[1] = "EUR";
   key[2] = "GBP";
   key[3] = "AUD";
   key[4] = "JPY";

   value[0] = 1.2;
   value[1] = 2.5;
   value[2] = 3.3;
   value[3] = 1.1;
   value[4] = 0.8;

   SortedByDouble(key,value);
