Daytraders After Market Lounge 6th July, page-26

It is my opinion that:
As you are treating trading as a business, one should have completed a 'business and professional items schedule' where all the deductions have been taken into account, resulting in a 'net profit (or loss)' figure. This figure is then inserted in the 'Net Income or Loss from a business' - Non Primary Production box. Schedule to be attached and lodged with the ITR. Keep a copy for your personal record.
