Oslo Stock Exchange Fights Back Against HFT And Quote Stuffing

Tyler Durden's picture


As High-Frequency-Trading rapes and pillages its way across global capital markets, perhaps it is no surprise that the country that gave the world 'Vikings' would be the first to stand up to the computerized hordes. In a breakthrough moment of clarity, The Financial Times reports, the Oslo Stock Exchange will issue punitive changes to traders if they send too many orders into the exchange that do not result in deals being done.

This first-of-its-kind crackdown on 'Quote Stuffing' comes after the exchange has seen a surge in the number of orders flooding its systems and while the bourse does not quite go so far as to say HFT is "in itself necessarily negative for the market", it says the placement and cancellation frequency of trades has reduced the efficiency of its market. Bente Landsnes, chief executive of Oslo Bors, said: "A market participant does not incur any costs by inputting a disproportionately high number of orders to the order book, but this type of activity does cause indirect costs that the whole market has to bear. The measure we are announcing will help to reduce unnecessary order activity that does not contribute to improving market quality. This will make the market more efficient, to the benefit of all its participants." From September 1st the exchange will limit each trader to 70 orders for every trade executed and any excess of that ratio will be charged $0.0008 per order. We are sure the NASDAQ, wanting to make up for its SNAFBU, will be next in line to punish the pernicious penny-pinchers.

Naturally, we fully expect those very much irrelevant, and lately totally tarnished US trading venues such as the now 'butt of all jokes' Nasdaq, to attempt to poach even more lowest common denominator HFT traffic from Europe, and provide even more "liquidity" rebates to Algo-Matic, in the process pushing electronic trading as a % of total nearly to triple digits.

Or by sending more vikings to the bank offices that do the trades.

Pretty soon with the S&P below its 200 day MA and Eurocalypse and Chuck Schumer and Mark Suckerturd and JPM and the algos fishing for sell stops, all signs are going to point to sell.  Unlike The Terminator, when the robots take (took?) over the world, they will not be shooting 4,000 bullets per second but 4,000 sell orders.

My guess is that this ends the Olso exchange.

Regulators get caught in hotel rooms with under-age girl scouts

or the exchange comes under sudden pressure and valuations drop mysteriously until the rules change back.

Still, hope for the good guys

I was thinking about that, it would help if it was randomized between .3 and 1 sec. (i.e 10,000 trades come in over 3 nano seconds, they are randomized .35,.99,.57,.36,.43,.42. It shouldn't affect real orders)

A randomized time-delay would be effective. And/or a miniscule per-share charge for every order or cancelled order.

The high-freaks of algo thrive by technology, but can be put down -- and easily -- by very minor tweaks to microstructure. Watch the dead red eye burn out.


Not surprised that a peripheral market like Oslo has moved first. Everyone looks to the U.S. and U.K. for leadership here, and lead we have and do -- in the wrong direction. Full-spectrum capture.

I was long ago saying to do this kind of thing...charge each unexecuted trade from quote stuffers .1 cent. That alone would shut down HFT's. 

And why not require every trade be executed only after a CAPTCHA is answered...hell everything else requires it why not a stock transaction?

It's a fucking fallacy to say that HFT brings in liquidity. It assumes that prices are rigid, that trading doesn't take place, unless there is liquidity. It's just like the fucking central banks want us to believe about asset prices. 

The underlying issue here is that perhaps the public equity market is not for everyone, that it is overextended and that a lot of public securities should have actually been funded in the private equity market!

Well done, Norway!

Well said ,,, HFT killed the floor traders and people that bought seats ,, ... the people that actually created liquidity when needed and acted upon real news and earnings rather than just milking order queues. I like the tax ... it can be adjusted (upward) until we get rid of the vermin.

Good strawman because before HFT front running never took place.

Same dead people did not largely engage in same activity as HFT which is basically what  caused their death, getting beat at their own game.



Thu, 05/24/2012 - 12:09 | 2459122 Assetman
Assetman's picture

Lets start with the first sentence:

Good strawman because before HFT front running never took place.

Before HFT, there were a myriad of methods to front run... in fact, very creative ways.  What HFT allows, though, is a method of skimming in massive volumes, and taking advantage of information in picoseconds.  It does nothing to increase the effeciency of the markets, because the liquidity it provides is done for the purpose of manipulation-- not true price discovery.  HFT is very efficient at setting up and executing front running scenarios, though.

Now, if you were trying to be sarcastic in that first missive, however, you might need more practice.

Lets go to the second sentence:

Same dead people did not largely engage in same activity as HFT which is basically what  caused their death, getting beat at their own game.

WTF????  Dead people don't trade.  It's because they're dead that makes it so challenging.

Now THAT was sarcasm.

Obviously, I'm am glad I am able to provide you with a most glorious laugh of the month based on your own preconceived notions of U.S. equity market trading operations.  Because most of the time, comedy really isn't my strongest suit.

I don't care how much I'm being skimmed as a retail investor.  I care than I'm being skimmed and front run in ways that are blatantly unfair-- and I see the evidence every single day as an institutional investor.  That alone is enough to keep me-- and thousands of other retail participants-- out of these manipulated markets entirely.

I hope that made you laugh even more, sweetheart.

Take your head out of your ass.

You did not post that. The other guy won post of the month for standing up for the former saints of Wall St, the floor trader.

You've been skimmed and scammed since the notion of a market became reality,

it is super laughable given how cheap it is to trade that folks such as yourself are so blinded with a need to be the victim, that the obvious is so elusive.

I could go on further regarding the delusion that somewhere that money found a less corrrupt market but seems pointless.

Oh stop it, Mr. Ferocious... now you're making me laugh.

I did not post what I just posted?  WTF?  More than half of what you say makes no sense whatsoever.  And the other half just isn't accurate.

Being a victim is YOUR term, not mine.  You plop your money down in an increasingly corrupt market as a retail investor and you lose that money, there is no one else to blame but yourself.  Your other alternative is not to participate.  I choose not to. Thousands of others have done the same.  The only trading that has increased to a significant degree over the past 3 years in the U.S. equity markets are those related to your self-endorsed HFT activities.  

I don't see anyone crying and claming vicitimization in these markets, save the investors involved in MF Global... and they were truly victims in every sense of the word.  

What I do see is people leaving these markets and not returning, because they see HFT for what it is-- a massive skimming operation that destroys true price discovery though the guise of providing liquidity and lower realized bid/ask spreads.  This is anything but 'cheap trading'... it's more like a wolf in sheep's clothing.

If it were not such a complicated issue, and listings could be placed on competitive exchanges worldwide, I'd place my money in Oslo well before I plumped down another USD in New York.  At least the NASDAQ is beginning to move in the right direction, though.

While I like that idea, another is to expand the idea of "short term" captial gains.  We peasants have to distinguish between assets held more than a year from those held less than a year.  Taxes could be raised again for assets held less than a minute, less than a second, or less than a millisecond.

A 50% additional tax on assets held under 1 second, 30% extra tax for assets held less than 20 seconds and a 20% one for assets held under a minute will fix everything nicely.

Uh yea it actually is the textbook definition of free market capitalism.

The regulatory response is typical of liberal socialism.  The notion that somehow they are going to level some playing field all the while they are wholly responsible for all of the unlevel fields in the world.

and NO, all forms of government move from less to more and end with none. There is nothing new or novel or special in this current existence.

at some point I am hopeful that even the biggest dolt recognizes this massive growth of governance the last centuries was brought to you by the rich and powerful for the sake of the rich and powerful and stop being so naive to believe more governance is going to benefit you in any way shape or form.

the endgame here? any higher costs to trade will filter to the bottom just like some ridiculous percent of taxation  and regulation is usually paid for by us at the bottom.

Old philosophies and labels like "capitalism" and "socialism" etc no longer apply. Mankind has created a new actor on the stage: computerized intelligence. Whether it's computerized drones that can kill us, robots that spy on us, robots that take our jobs, or quote-stuffing algos, we have not drawn the line between what's OK for a robot and what's OK for a person. We should acknowledge that we have created a superior species, able to think and act faster than humans ever will be able to. The question is what we do to control them before they control us any more than they already do.

Hate to break it to people, but NASDAQ has been planning something similar since early April.  Here's their latest implemenation plan:



Why are NASDAQ, BX and PSX instituting an Excessive Messaging Policy?

Robust liquidity provision, including depth of liquidity, is vital to modern equity markets and frequently updated displayed quotes generally promote efficient price discovery and provide essential liquidity. However, excessive quoting at prices away from the National Best Bid and Offer (NBBO) can result in a significant market data burden for participants and does little to improve the quality of the lit marketplace.

NASDAQ, BX and PSX are proposing an Excessive Messaging Policy that encourages active quoting near the NBBO while discouraging excessive order activity away from the inside. In this way, the exchanges seek to reduce non-marketable quote activity while protecting legitimate market making activity from incremental complexity and cost.

What is the Excessive Messaging Policy?

UPDATE 5/21/12:EffectiveJuly 2nd, NASDAQ, BX and PSX will introduce a policy intended to reduce excessive submission of non-marketable displayed orders to the exchange.

MPIDs that exceed a "Weighted Order-to-Trade Ratio" of 100:1 will pay a fee on the orders that cause them to exceed the threshold.

Order and trade activity by Registered Market Makers in their registered securities will be excluded from the ratio calculation.

What is the Weighted Order-to-Trade Ratio?

The Weighted Order-to-Trade Ratio is a measure of how often an MPID sends displayed, non-marketable liquidity-providing orders to the exchange that fail to execute.

It is similar to the "Orders to Orders Executed" ratio used by NASDAQ's ISP program, but also applies a Weighting Factor to each order based on its proximity to the NBBO at the time of entry.

UPDATE 5/21/12:The proposed weighting factors are:


Order's Price vs NBBO upon entry Weighting factor 0 - %0.20 away 0x %0.20 - 0.99% away 1x 1% to 1.99% away 2x 2.00% or more away 3x


Which order types are included in the Weighted Order-to-Trade Ratio calculation?

Only displayed, liquidity-providing orders received during regular market hours will be included in the Weighted Order-to-Trade Ratio calculation.

Non-displayed orders, Immediate-or-Cancel (IOC) orders and Auction orders will not be included in the calculation.

Orders sent by Registered Market Makers in their registered securities will not be included in the calculation.

UPDATE 5/21/12: MPIDs sending less than 100,000 Weighted orders daily will not incur penalties. Previously, MPIDs submitting fewer than 1,000,000unweightedorders were not subject to the penalty.

What will the penalty be for sending excessive messages?

UPDATE 5/21/12:MPIDs that exceed the Weighted Order-to-Trade Ratio threshold of 1,000:1 will pay a $0.01 per order penalty for their "Excessive Orders." MPIDs that exceed the Weighted Order-to-Trade Ratio threshold of 100:1 but less than 1,000:1 will pay a $0.005 per order penalty for their "Excessive Orders". Excessive Orders are orders that cause an MPID’s ratio to exceed 100:1. For example:

  • ABCD sends the following displayed, liquidity-providing orders:
    • 1,000,000 orders at the NBBO (weighting factor: 0x), of which 7,000 trade
    • 500,000 orders 1.5% away from the NBBO (weighting factor: 2x), of which 1,000 trade
  • ABCD's Weighted Order-to-Trade Ratio is 125:1
    • Weighted Order Count: 1,000,000 (1,000,000 x 0 + 500,000 x 2)
    • Orders executed (i.e., Trades): 8,000
    • Therefore, the ratio is 125 = (1,000,000 weighted orders / 8,000 orders executed)
  • Based on 8,000 orders executed, ABCD needed a weighted order count of 800,000 orders to meet the 100:1 threshold
    • Therefore, the Excessive Order quantity is: 200,000 = (1,000,000 - 800,000)
    • ABCD will incur a penalty of $0.005 on their 200,000 excessive orders.

UPDATE 5/21/12:Pending SEC review, theExcessive Messaging Policy will become effective July 2, 2012. This delay will allow members additional time to upgrade their systems to OUCH version 4.2 or 3.3. These versions of OUCH provide the "weighting factor" for each order entered, allowing firms to manage their weighted order count in real-time. Please refer to the postedOUCH specifications.

Where can I find more information?

Great post.

My impression is that these are tiny steps, and it still leaves some room for blatant manuipulation.  The scaled penalties on orders well beyond NBBO is a feature I really like.

What I don't like is the weighted order to trade ratio (100 to 1, really?) still allows the opportunity to skim on a flooded book of orders, but does at least place some ceiling on the abuse.

The provision that MPIDs with less than 100,000 weighted orders daily will not incur a penalty still leaves the wind open for some abuses.  That being said, in the realm of HFT, that daily threshold level can be really really small in the scheme of the crappy quotes they actually throw out there.

What I don't quite understand... is this $0.005 fee a penalty per order?  If you charge a fee only a half a cent on 200,000 orders-- that won't change behaviors very muchat all.   If the penalty is a half a cent per order (200,000 * $0.005 per order = $1,000), that level might eventually make a dent, but the profits captured on the quote stuffing may greatly exceed the penalties.

This would likely only affect the most eggregious offenders who put in 10000 orders per second.  For most others it would be a cost of doing business or they can just rewrite the algos to force a fill every 69 orders on 100 shares.  These guys trade millions of shares a day.  

The one and only way I see to stop this bullshit is to enact a minimum live time of a few seconds.  If you put an order in, it has to be live for at least 3 seconds for example.  

The other thing that can and should be done is to force them to actually have money for all the orders they have out there.  Since the algos are trying to manipulate price by quote stuffing, I would bet they never have the capital to pay for all those orders should they be filled.  Since they are placed and cancelled so quickly there is next to no chance they do get filled on 99% of them.  Force them to abide by Reg T rules when they place an ordder.  If you put in 10,000 orders you have to have sufficient buying power in the first place.

If I open an account at IB, they will not let me put in orders for 1,000,000 shares of MSFT unless I have money to pay for the orders.  This would include bidding 20 bucks below the market - it does not matter.  Hold these HFT to pay to play rules and it would additionally stop a lot of the games.

The cynic says:
Great, and it only took you how many years to implement something against this abuse?

The seasoned cynic says:
If they're implementing something now, it only means another new way to game the system has recently been discovered and successfully run.

"Order and trade activity by Registered Market Makers in their registered securities will be excluded from the ratio calculation."

"Only displayed, liquidity-providing orders received during regular market hours will be included in the Weighted Order-to-Trade Ratio calculation."

"Non-displayed orders, Immediate-or-Cancel (IOC) orders and Auction orders will not be included in the calculation."

In other words, orders that would never be published to the public (displayed) book and disseminated via ITCH are not included.  These are orders that are currently invisible to everyone but the exchange (aside from Auction orders), and thus could not cause any overload issues usually associated with 'quote stuffing' (except for the potential to overload the exchange's servers).

more people would be on board with socialism if they lived in smaller culturaly homogenous countries. Shared belief systems make it work. If you live in a big melting pot country then its capatalism and every man for himself.

Every thousand bids will only cost $8, if they are caught and fined at all.  too little, too late.

Nice idea but not fluid enough. As there's an incentive from market-maker trading to pay for trades even if they are losing trades, there should be a cut-off on that, or a penalty-fee per-trade exceeding the bonus given by the market-makers' friends. Do that & whatever the prices each are, the balance will limit back out. Either one drops the incentive or another increases the penalty to match & exceed the incentive.

That pretty much says it all.

It took me about 20 seconds to figure out how to circumvent this.

HFT launches 69 buy limit orders with intent to cancel.

HFT buys 100 shares @ market filled

HFT sends another 69 orders with intent to cancel.

HFT sells 100 sharse @ market.


You could do this all day long.  HFT trades millions of shares per day.  This would only hit the most extreme HFT bots that put in 10000 orders per second or some other garbage.  All you have to do is change the algorithm to make sure you are filled on 100 shares every 69 orders.
