Every broker is different - a lot of them offer no T anything service at all ie if the actual free cash is not in your acc, you cant even place an order

ie Etrade, Bell Potter, CMC, Nabtrade

Then theres others that are genuine T3 and you dont even need any cash or shares in the account at all ie some hobo from the street can open an account with zero cash or shares and the next day buy $25,000 worth of dodgy 1c microcaps and not have to pay anything as long as they sell the next day, the day after that or the day after that.

Try opening up 4 of those accounts as a newbie daytrader with no cash, no assets and no experience and see what sort of hot water you get into.
