Only on the point that they can queue jump... pretty sure they can't.
Any trade has to line up, or pay the premium. ASIC Sunk their gummies into this a couple of years back, when they addressed some issues with dark liquidity.

Of course, they are highly advantaged with the very skinny brokerage arrangements, the potential for improved arbitrage with the dual ASX/Chi-x houses, and the criminally massive advantage of being able to see incoming orders before the rest of us.

Anyway IMO, we're near the perfect set-up for HFT. A ½ pip profit (with next to no brokerage) at our current SP 3.5c nets them a tidy 1.4% on the trade. Not bad for a nano-second's worth of activity.

At the moment, we are too small (and risky) for shorting activity, but so long as there is reasonable liquidity, the HFT's are here to stay. Matters little to me, but if i were a DT or a scalper, i'd be bloody annoyed!
