ato share trader question

Assuming that one has been classed by the ATO as a Share Trader....

When you work out your Purchases..
do the Purchases include parcels of shares that....
a)have only been bought AND sold in same tax year.
OR
b)have been bought that tax year, regardless of whether they have been sold.

ie the nub of the question is..how do I handle parcels of shares that have noy yet been sold.


Thx HC Gurus. ;-)
