This can be easily remedied by the SEC. All they have to do is start charging for excessive orders/cancels. That ends the gaming.
However, they are just too lame to pull this off. They need to force the exchanges to make changes to their order entry/order matching systems to track the orders/cancels by account. If they can't do it in real-time, they can do it retrospectively at end of each trading month. The account is then hit with a debit for the number of excessive orders with cancels.
i agree,it's a piece of cake(done by IB long time ago). but there is no need for that. all you really have to do is go back in time and simplify things. limit,market, maybe couple more of other types and that was it. ALLOW participants COMPETE THRU THE PRICE(without subpenny BS) AT ONE EXCHANGE. it's really simple.
this is one field ,where SIMPLE, TRANSPARENT,but STRICT regulations for ALL participants is actually needed and can be applied,but as we all can see-they(SEC) have no balls to even ban suppenny crap.
actually, i wouldn't mind to have small gvt transaction fee and ONE exchange,that would exists, on those fees. all orders go there,no f** rebates,no order flow crap. broker profit from commissions,exchange-from fees. ONE exchange.all other shady ECN's in every US city, trading same stocks,dark pools,etc-banned.
all data is free,open for public and avaliable for everyone at no charge. you want democracy? transparency? there. perfect place to try. no need to piss away trillions in iraq,you can try this at home. we needed it here.
