I would like to trade ASX stocks on an intraday basis via IB. Is there anybody who has experience in trading US stocks and aussi stocks on an intraday basis ?

Is there a better broker than IB e.g. in Australia with lower comissions. 6 $ is a lot compared to the US market.

I'm interested to find out if it is a similar kind of trading or if there are any pitfalls I better know in andvance.
As far as I can see from the volume the ASX 100 stocks should be tradable out of a 5 minute or 1 minute chart.

Looking forward to your comments.
