It is not the BOT trading that is annoying it is the two tier market that ASX is running. To get the cheap trading rates that BOT's get you have to put up $100k? I think. It is all on ASX site under professional traders. The ASX has gone along with this trading and actively promotes this. Whether it breaks other finance laws I do not know.If we could trade with 50cents brokerage then the playing field would be level.
