I use Metastock software and Paritech data as well, I will subscribe to a SMSF newsletter as my Accountant has told me twice not to 'trade' shares.
That is what our accountant stressed too. A super fund cannot be seen to be in the 'business' of trading shares. Your share investment strategy (which should be written down) will need to lose any reference to 'trading' shares; buying and selling shares is ok though.
