i bought two sets of dione (by accident) the two transaction show up seperate in the security portfolio.

profit calculations are still incorrect in the leaderboard

leaderboard should sort by total account value not just how much is in cash

limit order type needs to be a type not a string (limitorder.java)

[done]the notification service needs to use the system time not the clock time.
