Get out of here?!
I actually met Mark back in the day. Fascinatingly intelligent guy. INSANE bike enthusiast.
Oh, and like I had mentioned elsewhere, this "Spoofing" nonsense is just that ... nonsense. As I said there?
How do you prove "spoofing"? Ok ... let's just set aside the fact that Traders have been doing this since ... oh I don't know ... about the year 3,000 B.C.E., and I consider it the predatory nature of all market participants (as well they should ... how many of these auction shows that are popular on T.V. show participants doing something akin to this? How many times has Rick Harrison tried NOT to show interest, when he is interested in an item, and vice versa? I mean Good god ... )
How do we decide what is "feigned interest".
Well, according to this, it is posting relatively large number of limit orders on one side of the order book to make other participants believe there is pressure to sell.
Uhm ... I have a question ...
Just a small silly one ...
Again ... aside from the fact that Traders legitimately do this so as to NOT affect price in many cases, when they want it for X price ...
How do we determine intent?
Ever cancel a Limit Order you put in; and then re-enter the order elsewhere on the book?
Oops! You spoofed!
Ever have to trade in size, and knowing there is a Hybrid FIFO-pro-rata mechanism in place, to fill orders, and you need 3,000 ... so you put in the order for 5,000, knowing that you'll be filled for less, and wala, you get 2,725 filled, and you cancel the rest of the order?
Oops! Did you spoof?
It's a nonsensical rule, that is open to interpretation, and dare I say? Is used to scapegoat traders when politicians want to feel like they are "being aggressive" against "those nasty traders"
