right. I cant think of the answer either. All I can think of is throwing in false orders on the other side of the market to spook others into jumping ahead. ie if youre buying then throw in false sell orders, big ones, so other sellers jump in front and hit your legit buy orders. Only as soon as you do that some one will lift your (phony) sell order and then youre screwed... apart from being illegal as well... I think talk of people/ brokers doing this is somewhat exaggerated (?) for the first reason above more than the legal one. I have heard of brokers pooling together small parcels to make one big order as well... but again im sceptical...
