If I'm a trader,
I'm holding $10,000 of shares going into the fin year.
I sell them for $20,000.
I buy $20,000 worth of another stock and I'm holding them at the end of the fin year.
Do I pay tax on the $10,000 profit from the sold shares???
Or do I pay tax on $20,000, the $10,000 profit and the $10,000 difference in opening and closing stock???
