What do people recommend as the best on line trading Co for quick trades and also for identifying market movements.

I am with Commsec, but I find the data very limited, especially in relation to seeing the market react to the up's and downs of the day.

I also would like to be able to see more than the top 20 trades, maybe even market sector/indusrty specific moves.

The other issue I have with Commsec is that I am unable to see where my trade is in the queue.

Thoughts opionions gratefully recieved.
