Im just curious, Im somewhat new to Excel.
I am starting to do stock market trades.
For Tax purposes, I have to report my cost - and the Revenue gained so that
I can be taxed on only the profit. Not only that, I have to report if it is
long term or short term.

In order to help me calculate Cost, Is it not best to set up a FiFO system?
if that is the best way, then how do I impliment a nice spreadsheet that
will help me with this? or is one already avaliable?
