jerkstore,
True. Though, you are making a case for market makers, rather than HFT's.
i'm making a case for all short term trading. it all breaks down to the same thing. short term traders trade at the expense of long term traders at the cost of the spread but provide the valueable service of tightening them through their activity which saves long term investors in the long run.
Did any of you take debate class in hi school? Remember how it was important to agree upon term definitions at the beginning? Market making and HFT strategies have become like concentric circles in the stock world--making this discussion difficult.
it doesn't matter what you call it, as it's all the same thing. the allegations are that the smallest of the small time frames are making money at the expense of everyone else (true), but everyone disregards the savings they reap as a result (which unless you're measuring it, you wouldn't know). instead, the song of the day is to associate losses or lack of knowledge of the use of trading tools with this group (who rarely have losses due to the enormous frequency, and who have EXCELLENT understanding of the tools).
The order information disseminated to some dark pool operators (which is what I would refer to as flash quotes) and some dark pool participants as well as order internalization (basically just a one market maker dark pool) gives a select group of well connected players huge, unfair advantages.
have you actually done any research into the logistics of being a liquidity provider and receivign IOI's in these pools? if you had, you'd realize the barrier to entry is a lot lower than you're implying. however, this is what everyone implies to make it sound more unfair than it is.
RegNMS only covers the public exchanges. Therefore if a dark pool operator has internalization deals with retail brokers (like Citidel does with E-Trade), all they have to do is sub penny the public exchange prices to legally internalize these non-public orders.
rgt, but how exactly is this a bad thing? if i'm the liquidity taker, i just got price improvement. if i'm the liquidity provider, i just beat the spread in the public market. if you and i decide to do a deal privately between the spread of a public exchange on a stock i own, why should that be illegal? if i'm providing value to you in the sale above the public market, then i don't get how we're doing anything wrong, and if i'm not providing value, you obviously have the option of using the public market.
If Citidel/Getco/GS/Knight/IB chooses not to internalize the trade, they can still use the order info to make proprietary trading decisions before that order ever hits a public exchange. This company may be making markets on a public exchange, but they are basing their public markets off of non-public order flow information. Read the fine print when you sign up as a Sigma X customer, which states that GS may make trading decision off of your order if you don't believe me. If that isn't the defintion of front running, I don't know what is.
sorry, this isn't front-running. how can it be if you know ahead of time that you're sending an IOI message to the pool? you trivialized it by saying 'read the fine print', but in fact, that's an important part of understanding the business you're involved in. if it's important that no one know about your order before it routes to public exchanges, then you don't route to dark pools with IOI's. period. likewise, even if you understand that there's a potential that there will be information leakage, but OVERALL your analysis shows significant cost reduction using the route, then you continue.
This kills liquidity for all other participants who don't know the orders coming through the pipeline. All the while, the HFT company may adjust theoretical values due to non-public information. This sucks liquidity from everyone else, and hands it to the HFT company.
again, if there wasn't value in using dark pools, firms wouldn't route there. 'sucking' liquidity from public markets is hyperbolic. it would be more accurate to say dark pool liquidity due to its cost structure and inherent efficiency are out-competing public markets that are hampered by regulation.
Similarly, in the options world, payment for order flow is a liquidity killer. If a company is a registered market maker, they must pay .65 per contract every time they trade with a customer counter-party. Since dark pools do not fall into the same regulation, HFT companies register as customers in the public exchanges. These companies send .5 cent wide markets into dark pools. If they get hit on a trade, they cover by routing the exact opposite trade via naked sponsored access brokers into a public exchage. Since they come in as customers and get paid .65 cents per contract, they literally can buy and sell the same price, and make money. This is killing the market making companies. Think about a penny wide market in an options product. A HFT company can sub penny both sides, and still make money. Whereas, after adding together all the fees, a market making company would need at least 2 pennies of edge to break even.
again, this another example of a public market being outcompeted by its private counterpart. this isn't an hft issue, this is a cboe issue. they're killing their own market makers with a transaction based cost structure for MAKING markets. idiotic. from my view of your description, the hft market makers are arbing the cboe and providing price improvement to customers. bravo. that's how a market should work. there's two solutions to this, the cboe will have to adapt if it wants to stay competitive, or regulation will prevent the dark pool markets from quoting allowing cboe anit-competitive rules to continue.
The HFT companies do not hold positions. They change their markets based on non-public info. They are killing the real liquidity providers. Adding all this together results in the marketplace losing the price impact cushion to order flow, which pure market makers used to provide. HFT decreases liquidity and vastly increases the price impact that orders have in the marketplace. The penny wide displayed market is an illusion.
This is not a good thing for the market in general. More flash crashes with .01 @ 10000 type of markets are in our future, if we continue to allow HFT trading methodolgy to be legal.
so, where were the 'real' liquidity providers during the 'flash crash'? gimme a break. the buyside DESTROYED the bids, hft or not, no one was stepping in front of that train. did you any math on the amount of size going off on the bid on HUGE dow components? on corp bonds? there's only so much you can expect the market can take and it took A LOT. do you have any data that shows the market SHOULD have been able to absorb those orders? pull up the time and sales for PG. it WASN'T a fat finger. this was one of MANY. how much went off? come on, you sound intelligent, do your homework here.
the 'flash crash' is what happens when you let big dumb boys play with dangerous toys. exchanges should provide the tools to prevent the idiotic from destroying everything. again, this has zero to do with hft and it's pure crap you're trying to pin it on them.
