No-one would listen. The exchanges like the ASX are paid off by high-frequency traders to allow them to front-run trades and use algorithmic trading by paying a heavy subscription to do so.
It's so bad in NY for example, that they have to have a certain length of fibre-optic coiled up so they don't have an undue advantage over the other HFTs and are that close in milliseconds.
ASX, and others, might nod their collective heads and say "oh yes it's naughty, it's bad" but they're not going to stop it, when they're getting millions of dollars out of it.
These traders are helping to suppress, and damage the stock price, sometimes on behalf of the market-makers and institutions who are slowly accumulating. That's the way I see it anyway.
It hurts the small, independent traders, creates artificial trading environments, and hides the substance of the company and fundamentals. On days when you believe it should be soaring, they are selling into it, and vice-versa.
If the stock was a dog, they would leave it alone, instead they're all over it like a fat kid on cake for over 6 months now.
