I used to just print out my buy contract and then staple my sell contract together,,
Then just minus the capital gain or loss and then minus the GST then minus the brokerage,
It equals a net result of a profit or loss,
Peice a piss mate,
Depending on how often you trade will depend on how long you have to sit there, lol,
Then do the next one,
Then I made up an excell spreadsheet that all I had to do was enter the code, amount of shares, amount or brokerage amount or GST and the the sell date,
I got a bit lazy so couldn't be bothered after about 6 months,
I even had a running trade entry book I made up, got lazy and couldnt be bothered,
Now I just staple the buy contract to the sell contract then just plus or minus,
