Personally I hate the auction queue jumpers.
One can have a buy at say 5c waiting for weeks. Then one morning a seller turns up with 300,000 to sell at 5c before open. And a millisecond before trading a queue jumper comes in and snatches 299,999 of them.
But the asx won't change it I guess, as it means more trades. And I must admit to being the queue jumper at times too!
