Balance of your account as in seeing the difference between your buys and sells?

You will need to do a search through your confirmation tab (under trading tab) then in the summary area has total buys and sells.

Transaction tab is only to work out what ComSec owes you or what you owe ComSec. There is three amounts due to it needing to balance the books to 0.00.

If you have a buy for 1000.00
A sell for 1100.00
Currently there is 100 need to be paid to you from ComSec to get the balance back to 0.00, hence the reason to have 3 transactions to the trade.
