you can never trade at a loss due to tax if you make a profit on your trade after brokerage. This is because the gov only takes a % of profits leaving you with some. Also u get a % back from brokerage. But if you end up ahead after counting for brokerage there is no way the tax man can make it a loss. Also CGT for me is not 50%.
CGT is taxed at the personal tax rate unless the asset is held for more than a year in which you pay 50% LESS
