RXM along with most other ASX300 listed stocks have many of these high frequency traders - they do not pay brokerage per trade.

They pay an annual subscription to get their HFT account.

They do act on behalf of normal traders too sometimes - like UBS do for my super fund they sometimes bleed the order through in dribs and drabs and other times in one hit depending on who is on the other side of the trade i suppose.
