it's not commsec or etrade, page-2

i've never done or tried this before, so i just thought for the hell of it, i thought i'd try to place an order with comsec for an unmarketable parcel, i tried to place an order for ONE share at 9.5 cents, and then 5000 shares at 9.5 cents(value $475) and failed on both occasions. The following message came up...

Your order cannot be accepted due to the following reason.

So why should anyone else be able to do it ? If it's good enough for comsec to ban (and i daresay they have 10's of thousands of clients) then ASIC should put a stop to it immediately.
