Walter, I don't wish to sound rude, but you really have no clue as to how HFT programmes work...
I suggest you go and do some reading up.
I used to write co located news arb systems as well as market making systems based on stat arb principles. Those 'visuals' you posted at the start of the thread, a few of those looked pretty similar to the type of artifacts my MM system would make in volume and price as it would test the market. Since you seem to be a self proclaimed expert on the subject, I can only assume you have experience in the field as well?
