Return highest buy or lowest sell ticket number

[Adam Woods]

Hello Fellow coders,

I'm getting myself into a bit of a flap. I am trying to write a function so that it will return the ticket number of my highest buy trade or lowest sell trade, so they can be isolated from the basket and closed. 

I know I need to find the correct ticket number of the above trades so they can be returned into the function to close that ticket. I'm just not sure how to write it correctly any help or pointing into the right direction would be much appreciated.

Code:

//+------------------------------------------------------------------+
void CalculateAllPositions(ulong &ticket_highest_buy,ulong &ticket_lowest_sell)
  {
   ticket_highest_buy   = ULONG_MAX;
   ticket_lowest_sell   = ULONG_MAX;
//--- auxiliary variables
   double price_highest_buy   = DBL_MIN;
   double price_lowest_sell   = DBL_MAX;
//---
   for(int i=PositionsTotal()-1; i>=0; i--)
      if(m_position.SelectByIndex(i)) // selects the position by index for further access to its properties
         if(m_position.Symbol()==m_symbol.Name() && m_position.Magic()==InpMagic)
           {
            if(m_position.PositionType()==POSITION_TYPE_BUY)
              {
               if(m_position.PriceOpen()>price_highest_buy) // the highest position of "BUY" is found
                  ticket_highest_buy=m_position.Ticket();
               continue;
              }
            else
               if(m_position.PositionType()==POSITION_TYPE_SELL)
                 {
                  if(m_position.PriceOpen()<price_lowest_sell) // the lowest position of "SELL" is found

                 }
           }
  }

               if(m_position.PriceOpen()>price_highest_buy) { // the highest position of "BUY" is found
                  price_highest_buy=m_position.PriceOpen();
