With Trader dealer you need to do 20 trades a month & then it's free - otherwise I think they charge a $38 ASX fee & $38 for use of platform (?) for that month..?
I've never had to pay yet but if you're online all the time & plan to do a few trades then one trade grabbing you $100 profit would cover the fee if you're less than the minimum trades - the brokerage fee is $33 for a buy or sell but with that fee you can enter a stock as many times a day as you like for no extra as long as you don't use more than six different price ranges
ie. trade say RRS & get in/out several times & still only pay the one fee - remember that Etrade also charges for stoplosses while they are free with this one so take that into account ...
Anyway, the 'webiress' platform is the best I've used & I tried 9 different brokerage sites before I picked it (years ago) but choose something that suits your own trading style best....good luck
