How to use the OrdersTotal()

int OpenPos()
{
   int total=PositionsTotal();
   int count=0;
   for (int cnt=0; cnt<=total-1; cnt++) 
      {
         if(PositionSelect(Symbol()) )
            {
               if(PositionGetInteger(POSITION_MAGIC)==MagicNumber)
                  {
                     count++; 
                  }
            }
      }

    return(count);
}
