Quote from Bob111:
in "hit and run" book by cooper he "reveal" his trading system ,where he step on front of big order, hope that stock will run up, driven by this big buyer.. what you describe(and what i saw every day on not very liquid stocks-just opposite to this moronic strategy. after big size pop up, there is immediately bunch of Cooper followers shows up and start beat each other with bids one penny above each other..after bid is high enough and there is enough idiots on front of this big buy order-seller simply unload his stack(not been shown before) and all idiots are get filled. then big order all of sudden-disappears. done deal and everyone is happy))))
