I used AOT online until recently when they started giving me the shites. Wanted the data and not the attitude. be careful though, when you really need it there is a problem with AOT that causes the market depth to not be really what is happening.
I know this because I use a full service broker to execute (wouldn't know otherwise..)
Sure, may be more expensive but its got me out of the poo many many times and the extra brokerage pays for itself over and over again.
(Takes a few years and the right operator to figure that out though.)
