Ok, what about this.
I use my IB account to put an order in to lower the ask or raise the bid. I then use a totally seperate account (let's say my neighbors) to hit that new ask or bid.
a) Is that illegal
b) How would they know (investigation?)
c) Don't people do this sort of thing with stocks all the time?
d) If the two accounts are different, how would either of the firms internal systems detect anything amiss? As far as IB is concerned I'm just trying to buy an option at 3.70 instead of 3.80 and as far as the other firm is concerned, someone else just sold 10 contracts at 3.70 because there was suddenly an offer to buy at 3.70
