Ann: Quarterly Activities/Appendix 4C Cash Flow Report, page-26

It's pretty rigged, at least with commsec, you are currently unable to place a buy order at 0.009 as the order gets rejected "orderly markets" kinda stupid when it's the next available volume but due to the price difference cant be traded, I dont really think they should have blocks like this in place, the market dynamics due to % move per tick size makes no sense at all. Some stocks can move 100% in one tick and others 0.01% it's a broken system that needs fixing, the math logic in markets especially small caps is so dumb.
