I did an experiment this morning. Bought 3000 and sold 5000. Have worked out there is probably a lot of depth manipulation going on. It has been happening to me a lot in the last year or so. eg there will be an order sitting there for a while either buying or selling and it could be sitting there for 30min or an hour it doesn't matter, every time I amend my order I get the feeling someone is watching and quickly put there order ahead of mine. It has happen to me too many times to be a coincidence.:t_down: It has happened to me at least 6 times today and that is one of the reasons why I will give up share trading in the future at some stage. If someone on the inside can see your order coming through and quickly change theirs, then that is not good.
