Rogue Algorithms And Other Mutually Assured Destruction Program Trading Alternatives

Why Institutional Investors Should Be Concerned About High Frequency Traders
 
 
A Themis Trading LLC Mini White Paper
 
It is now generally understood that high frequency traders (HFTs) are dominating the equity market, generating as much as 70% of the volume.
 
HFTs are computerized trading programs that make money two ways, in general.  They offer bids in such a way so as to make tiny amounts of money from per share liquidity rebates provided by the exchanges.  Or they make tiny per share long or short profits.  While this might sound like small change, HFTs collectively execute billions of shares a day, making it an extremely profitable business.
 
Why should institutional or retail investors care?  After all, aren’t HFTs adding liquidity?  That’s what they and the exchanges, who court their business, say.
 
There’s a lot to worry about.
 
1.  HFTs provide low quality liquidity.
 
In the old days, when NYSE specialists or NASDAQ market makers added liquidity, they were required to maintain a fair and orderly market, and to post a quote that was part of the National Best Bid and Offer a minimum percentage of time.  HFTs have no such requirements.  They have no minimum shares to provide nor do they have a minimum quote time.  And they could turn off their liquidity at any time.  When an HFT computer spots a real order, the HFT is not likely to go against it and take the other side.  The institution is then faced with a very tough stock to trade.
 
2.  HFT volume can generate false trading signals.
 
This can cause other investors to buy at a higher price, or sell at a lower price, than they would otherwise.  A spike in HFT volume can cause an institutional algorithm order based on a percentage of volume to be too aggressive. A spike can attract momentum investors, further exaggerating price moves.  Seeing such a spike, options traders can start to build positions, which, in turn, can attract risk arbitrage traders who believe there’s potential news that could affect the stock.
 
3.  HFT computer servers are faster than other trading systems.
 
Because most HFT servers are co-located at exchanges, they can beat out institutional or retail orders, causing them to pay more or sell for less than they should have for a stock.
 
Then there are the “what if” problems that could be created by HFTs.
 
1.  What if a regulation like the uptick rule were enacted?
 
Volumes could implode and stocks that appeared highly liquid could become extremely difficult to trade with wide spreads and no depth in the quote.
 
2.  What if a “rogue” algorithm entered the market?
 
Many HFTs are hedge funds that enter their orders into the market through a “sponsored access” arrangement with a broker.  Many of these arrangements do not have any pre-trade risk controls since these clients demand the fastest speed.  Due to the fully electronic nature of the equity markets today, one keypunch error could wreak havoc.  Nothing would be able to stop a market destroying order once the button was pressed.
 
Gives new meaning to the term “mutually assured destruction?”

Nice educational piece.

Regarding point #3, wouldn't limit orders take care of this problem for retail investors?

 

I don't worry about most retail investors who invest in individual stocks, most are relatively experienced from what I have seen.   I worry more about retail investors putting money into mutual funds, or contribute (sometimes indirectly) to defined benefit pension plans.  Those stupid buggers could care less if they overpay (or undersell) a stock, they get paid either way.  that is how the retail investor really gets ripped off.

Experienced in getting good execution?  Yes, most aren't stupid enough to enter market orders.

Experienced in that they understand what they are investing in?  Not in most cases.

the point is, the real victims are the sheeple giving their money to professional money managers, who could care less if they get good execution.  these were the fuckers who allowed hedge funds to late trade, after all.  how quickly that whole scandal was forgotten.

BTW, that was another scandal where the useless SEC was asleep at the wheel; Spitzer handed them that one.

When I said "know what they are doing" I meant "know what they are getting into", not necessarily that they have any skill as traders.

it is hard to argue that your idiot roommate is getting ripped off on execution, he can choose to use limit orders if he wants, that way he only pays the price he wants.

whether or not that price makes any sense is his problem, and has nothing to do with HFT.

limit order only offers 1-sided protection based on whether it is buy or sell. the market may move after your order is submitted in such a way that you may not be receiving the cheapest buy (below your limit) or highest-value sale (above your limit) from the counterparty. the idea here is to not have to put a limit order on, necessarily, e.g. that liquidity is so high and trading so instantaneous that a market-order is truly what you see on the nat'l best bid/offer books...

 

naturally this isnt realistic...and it's what we're struggling against, while the SLPs reap benefits from rebates.

 

the article is wrong in what it says about not having minimum %'s of trading-day time to list best bid/offer for these rebate-incentivized participants... i'm sure in the past few days, many of us (if not most) have read, re-read and re-re-read the NYSE SLP and DMM rules....

<If something is wrong, or bad for you, why would you play?>

That is perhaps the most ignorant statement I've ever read.  If as our dear leaders tell us, functioning capital markets are essential for the survival of our economic structure, then clearly there must be some sort of organized rules to the game. Your hamburger example is valid only because someone can easily choose no hamburger.  Can any of us professionals choose no capital markets?

Do you make the same asinine comments when rules are tweaked in football to protect the players?  Ohh the babies can't handle being horse collar tackled, how can they let their freedom be taken like that.

By your logic I should have access to enriched uranium if I want.  Since, you know, setting rules for things is for commies.  There is a middle ground beetween FREEDOM as you describe it and having the hot breath of an SEC officer on my neck at all times.  And I would say that setting rules to limit how much power an algorithm can have over capital markets fits within that middle ground.

the problem with your argument is that these guys are not scalping you and me, who invest in indivdual stocks and ETFs and can decide to exit the market entirely, like many have done during this runup.  Our only cost is "opportunity cost".  the real victims are the sheeple who invest part of their paycheck week after week into their 401k, which has as choices 8 large cap mutual funds and 1 bond fund.

 

the same companies who are practicing HFT are pushing the sheeple to continue to pump money blindly into 401k accounts, to help feed their machines.  they exploit a known weakness in the system, while suppoting the continuation of that weakness.

While I dont know if I'd agree with you, based on your first statement, I do agree on the second one.  

 

Personally I'm all for regulation against fraud and misrepresentation, but tyring to prevent people from being stupid, i.e. making rules that lessen the requirement for people to be stupid, well you're asking for stupid people to start investing money then.  This would give, by default, new guys on the scene who will cut and run with clients money, equal footing with those who have honestly worked hard and built reputations.  Now reputations don't matter, since people are equally suspicious of all wall streeters. I feel so protected.

#1 Was rhetorical, howeverGlass-Steagall Act reinstated would be advantageous.

 

#2  Is a no brainer, banks and financial institutions take their own losses since they caused it.

So were comments #5968, 5970, 5973, and 5974 all written by the same Anon?  They all seem to be a thinly veiled defense of the status quo. You know, the same asshole status quo that knee capped this country and got disgustingly rich, (and richer by the day), in the process.

have not traded in years, but I remember when we were acting as liquidity for the markets, and i mean proprietary traders.  I only traded the NYSE and just when trading was getting good for us....actually beating the specialists at their own games- they started changing all the rules...  went to pennies, went to open book, took away married puts.  When the rules changed, the game changed.  I left, the old firm disappeared and has been relaced by computers.  The human element knew fear and kept us in check.  The computers know no fear, nothing to keep them in check.

Sup, Tyler.

Points 1 and 2 are directly related to 3. The funny part is how everyone is wailing like a drunken Irish widow over the grave of market parity because of agnostic middlewares HFTs run their algos on. While some top shelf shit, that's not how GS is leading everyone by and through the nose.

There was recently a change over in this theater of the absurd no one noticed, or would have noticed, except a dude got sloppy. Real sloppy, but even then people are just popping popcorn and shoveling down meta because that's just what people do.

No one wants to admit they don't know the plot of the movie they are watching, not even to themselves.

They live their lives in the darkness of the matinee, it's their escape. Can't really blame them, it's what they've been trained to do. Nothing. If they knew the reels of their reality were constantly be changed seamlessly before their eyes, they'd burn the fucking theater to the ground.

No one likes being lied to, unless you are lying to yourself.

Well, let us scream fire in the theater, Tyler.

STORM had Jack's shit to do with the algos running on the fronts for HFTs, it's a datapump. They got you chasing robots in the controllers.

This cigarette burn has been seen before, back in the 90s when modems were helping people fill the empty voids in their life with the internet. Good times, that, people thought this would finally make them feel whole, that sense of belonging that real life just wasn't cutting. Another chance to consume to maybe taste happiness.

To help you out, GS just went from "hardware modems" to "software modems" using STORM. Don't be a fuck up and think I mean literal modems, it's an allegory. But on the backbone level, the software in question isn't their algos, it's how they are always first in the market place.

STORM has no components to slow down latency, it's all software.

This shit is ICE-9ing the flow of data, Tyler, almost freezing it in the middleware for the trading algos to work their magic almost at the speed of light, relative to the speed their competitors are getting the same data.

They can react many times over before the other poor sacks of shit even know what the market data says.

STORM being telecom is not issue, all middleware uses the tcpip of telecom, and being agnostic, they just plugged that shit in and the magic happened and no one saw the reel change.

Did you?

One therefore should lead to the other.

As corporate greed that drives the trade then whilst say GS is the frontrunner (an assumption) then others MS, DB, UBS will follow suite. All are equal and just a tad behind the implementation.

So shaving margins with immense volume then will be the state of the art trading. This leads one to speculate that too many players will create a far greater margin of error (compounding errors) which could create chaos.

Now implement that scheme into a casino, better still counting and what is the outcome? The ability to count destroys the table's margins signifcantly. Same would apply to the stock exchanges, except in the stock exchange it is other peoples money not the house that loses.

 

History has shown that not all programs are perfect as those that construct them are human.

 First thing they need to do is prevent 'first look' co locating scams.

 

 This is fraud, and the exchanges are making blood money supplying this data.

 

 Every market participant should have the same access to data timeframe wise. Anything else is cheating.

 

 There's nothing that can be done about internet latency, but letting GS and the other leeches  sit 5 inches from the quote servers is an abomination.

I agree with the exchanges making blood money by offering the location of matching engines. they for lack of a better term 'rape you' in terms of priceing.

 

every participant has access to the data timeframe wise. just some of us want to have better seats to watch the game.

i take what you said as if i go to a baseball game, i need to sit way out there and i am not allowed to buy better seats to get a closer view.

its the same game that went on in pits. you stood next to the big broker, you got the great fills, you had a horrid spot, you got the crap. some of us want the better fills and we need to do that buy buying the better locations.

 

now what i am talking about is is pure liquidity providing. NOT taking markets. that crap just plain sucks.

As an aside, I'm surprised at the kid glove treatment JPM has received thus far here on ZH.  Seems to me, (granted I have no background in finance), JPM is just as bad as GS.  Please let me know if I am wrong, (I'll still think they are assholes regardless)
