Cutting Through The HFT Lies: What Really Happened During The Flash Crash Of August 24, 2015





One of the fallacies being propagated about yesterday's flash crash, is that somehow HFTs came riding in as noble white knights and rescued the market from a collapse instead of actually causing it. This particular lie is worth a few quick observations and explanations of what really happened.

One Trader's FOMC Take - "A Rate Hike Is Coming And It Is Not Priced In"





A rate hike is coming. It is coming because the economy is not in crisis and zero rates are crisis rates, Bloomberg’s Richard Breslow writes. It is coming because the benefits of starting down the path to monetary policy normality are vitally important to the future health of the economy and restoring the Fed’s reaction function. The world can share the benefits and the costs. But one thing we do know, is that with all the hinting and polling and talk of trajectory, it is not priced in.

6 Years And One Witch Hunt Later, Goldman Changes Its Mind On "Secret Sauce" Software





Despite the firm's rather checkered history when it comes to open source software, Goldman is reportedly set to make some of its technology available to clients. This new, enlightened stance comes six years after the bank accused a former employee of stealing code that, if it fell into the "wrong" hands, had the potential to "manipulate markets in unfair ways."

The $12 Trillion Fat Finger: How A "Glitch" Nearly Crashed The Global Financial System - A True Story





... in under a minute, the hateful script had taken offline the entire system in much the same manner as chucking a spanner into a running engine might stop a car. The databases, as always, were flushing their precious data onto many different disks as this happened, so massive, irreversible data corruption occurred. That was it, the biggest computer system in the bank, maybe even the world, was down. And it wasn't coming back up again quickly. At the time this failure occurred there was more than $12 TRILLION of trades at various stages of the settlement process in the system. This represented around 20% of ALL trades on the global stock market.

In Latest Market-Rigging Scandal, ITG Busted For Frontrunning Clients In Its Dark Pool





Since the market is once again on the verge of a terminal liquidity seizure with its associated side-effects (see China for details), the authorities needed to remind the "market" just who the scapegoat will be when the next crash finally does come. Which is why earlier today in an unexpected "preliminary second quarter guidance" release, ITG, owner of the Posit dark pool, was just busted with a $22.6 million potential SEC settlement for what appears to have been blatant frontrunning of company clients in its own prop trading pod. But what is particularly amusing in this case is that while everyone knows that when it comes to HFT's, it is never called "rigging" - the proper nomenclature is "glitch", so now we learn a new term to use instead of "criminal frontrunning" - drumroll... trading experiment,

The Irony Of Market Manipulation





Having gazed ominously at the extreme monetary policy smoke-and-mirrors intervention in bond markets, and previously explained that "the stock market is to important to leave to the vagaries of an actual market." While the rest of the world's central banks' direct (BoJ) and indirect (Fed, ECB) manipulation of equity markets, nobody bats an eyelid; but when PBOC steps on market volatility's throat (like a bull in a China bear store), people start complaining... finally. There is no difference - none! And no lesser Asian expert than Stephen Roach warns that we should be afraid, very afraid as he states, the great irony of manipulation, he explains, is that "the more we depend on markets, the less we trust them."

This Is What Happens When The US Treasury Market Is Taken Hostage By "Malfunctioning Algos"





"In some instances, malfunctioning algorithms have interfered with market functioning, inundating trading venues with message traffic or creating sharp, short-lived spikes in prices as a result of other algorithms responding to the initial erroneous order flow."... "If liquidity is as bad as it is now, what’s going to happen when things really get adverse?” said Richard Schlanger, who co-manages about $30 billion in bonds as vice president at Pioneer Investments in Boston.

SkyNet Is Almost Sentient: HFTs To Start Trading Bitcoin





As noted earlier, with equities now a barren wasteland of volume (and liquidity), the last remaining HFT master (of whale order frontrunning) has been forced to go to those asset classes where organic flow is still abundant such as FX, courtesy of central banks engaged in global currency wars. However, HFTs realize it is only a matter of time before FX order flow also dries up as central banks take their trade away from public venues (and dark pools) and as such are always looking for new, untapped markets. One place where they are about to land according to the WSJ, with hilarious consequences sure to follow, will be the one place that HFTs should have felt at home from the very beginning: bitcoin.

Both SEC And FINRA Admit That The Market Is Rigged (And They Are Powerless To Fix It)





"When an HFT that is not a member of an association executes an off-exchange trade, the HFT’s identity is usually not reported to the Financial Industry Regulatory Authority, or FINRA, which is the only association currently in existence. This frustrates FINRA’s surveillance efforts as it cannot quickly link trades to the HFTs responsible for them. This is a serious problem because, according to FINRA’s current Chairman, certain market participants disperse their trading activity across multiple markets in an attempt to hide various forms of market abuse, including layering, spoofing, algorithm gaming, and wash sales."

- SEC Commissioner Luis Aguilar.

This Is The HFT "Malfunction" That "Roiled" The Market And Cost Citadel $70,000





Back on June 3, 2013, following what was merely the latest observation of how broken the market is thanks to central banks manipulation and HFT rigging, we wrote some snarky commentary.  And as happens with nearly 100% regularity nowadays, our snarky commentary on what takes place behind the scenes was once again almost 100% accurate. Because earlier today we learned precisely what happened...

Is The US Preparing To Blame The Next Market Crash On "Russian Spies" And HFT?





Spy 1: You can ask about ETF. . . . E-T-F. E, exchange.
Spy 2: Yes, got it.
Spy 1: How they are used, the mechanisms of use for destabilization of the markets.
Spy 2: Aha.
Spy 1: Then you can ask them what they think about limiting the use of trading robots. . . .

US Treasury Warns Investors Underestimate "Potential For A Market Reversal", Take "Low Volatility For Granted"





"Investors may have taken low volatility for granted and underestimated the potential for a reversal. While quantitative easing policies are intended to encourage investors to buy risky assets, there is also a risk that the perceived reversal of such policies will lead investors to turn the other way, triggering market instability.... Similarly, investors may have become too sanguine about the availability of market liquidity — the ability to transact in size without having a significant impact on price — during both good times and bad. Accommodative global monetary policy, coupled with the Federal Reserve’s purchases of large amounts of low-risk assets and changes in risk sentiment, helped to compress volatility and risk premiums.

"Real" Stock Volatility In October Highest Since Lehman





While VIX pumped-and-dumped (in a manner never seen before in its history), 'real' volatility of the day to day moves across the major stock indices remains extremely elevated. For the Nasdaq and Dow Transports, the average true range over the last few weeks is the highest since the post-Lehman collapse...

If You Like Your Broken Markets... Treasury Futures Edition





"If you like your broken markets," it would appear you can keep them... but this time in bond futures. June 2015 30Y Futures prices are surging today (up a stunningly fat-finger-esque 7.4% (or 10 points)). This, however, is being traded... there is volume being exchanged... and at 151-19/32, it implies 30Y Bond yields will be below 2.4% by the middle of next year (from 2.99% today).

How Germany Defines, And Deals With, HFT Market Abuse





"The HFT Act will add the following clarification to the rules specifying the prohibition of market abuse: The placing of purchase or sale orders to a market by means of a computer algorithm which automatically determines the parameters of the order could be considered market abuse provided the placing of orders occurs without a trading intention, but (a) to disrupt or delay the functioning of the trading system, (b) to make it more difficult for a third party to identify genuine purchase or sale orders in the trading system, or (c) to create a false or misleading signal about the supply of or demand for a financial instrument."
