how does this happen?, page-2

Hi Lucky, i've been wondering the same thing. cxa trading is parallel to asx so that can trade and bypass the current head of buy list as comsec is asx. I have recently had the same happen to me. There is a hidden order option on commsec which seems to override normal orders. i also think comsecs own orders get priority over ours. On the other hand if we pay up to get a position ,sometimes part of the order is filled at lower price, prob from hidden order. Just wait till a stock is running bigtime ,commsec can't process the volume of buys sells and we can't get our order to be accepted.On 2 occasions i missed 50k profit due to not being able to get order on.
