The Day The Market Almost Died (Courtesy Of High Frequency Trading)

A year ago, before anyone aside from a hundred or so people had ever heard the words High Frequency Trading, Flash orders, Predatory algorithms, Sigma X, Sonar, Market topology, Liquidity providers, Supplementary Liquidity Providers, and many variations on these, Zero Hedge embarked upon a path to warn and hopefully prevent a full-blown market meltdown. On April 10, 2009, in a piece titled "The Incredibly Shrinking Market Liquidity, Or The Black Swan Of Black Swans" we cautioned "what happens in a world where the very core of the capital markets system is gradually deleveraging to a point where maintaining a liquid and orderly market becomes impossible: large swings on low volume, massive bid-offer spreads, huge trading costs, inability to clear and numerous failed trades. When the quant deleveraging finally catches up with the market, the consequences will likely be unprecedented, with dramatic dislocations leading the market both higher and lower on record volatility." Today, after over a year of seemingly ceaseless heckling and jeering by numerous self-proclaimed experts and industry lobbyists, we are vindicated...absent the last minute intervention of still unknown powers, the market, for all intents and purposes, broke. Liquidity disappeared. What happened today was no fat finger, it was no panic selling by one major account: it was simply the impact of everyone in the HFT community going from port to starboard on the boat, at precisely the same time...It is time for the SEC to do its job and not only ban flash trading as it said it would almost a year ago, but get rid of all the predatory aspects of high frequency trading, which are pretty much all of them...HFT killed over 12 months of hard fought propaganda by the likes of CNBC which has valiantly tried to restore faith in our broken capital markets. They have now failed in that task too. After today investors will have little if any faith left in the US stocks, assuming they had any to begin with. We need to purge the equity market structure of all liquidity-taking parasitic players. We must start today with High Frequency Trading...

Web of Debt - COMPUTERIZED FRONT RUNNING: ANOTHER GOLDMAN-DOMINATED FRAUD

Ellen Brown

While the SEC is busy investigating Goldman Sachs, it might want to look into another Goldman-dominated fraud: computerized front running using high-frequency trading programs...Wall Street commentator Max Keiser...claims to have invented one of the most widely used programs for doing the rigging. Not that that's what he meant to invent. His patented program was designed to take the manipulation out of markets. It would do this by matching buyers with sellers automatically, eliminating ``front running'' -- brokers buying or selling ahead of large orders coming in from their clients. The computer program was intended to remove the conflict of interest that exists when brokers who match buyers with sellers are also selling from their own accounts. But the program fell into the wrong hands and became the prototype for automated trading programs that actually facilitate front running...Keiser and HSX co-founder Michael Burns applied for a patent for a ``computer-implemented securities trading system with a virtual specialist function'' in 1996, and U.S. patent no. 5960176 was awarded in 1999...The listing for Keiser's patent shows that it has been referenced by 132 others involving automated program trading or HFT...

Not with a Bang but a Whimper -- The Risk from High Frequency and Algorithmic Trading

Rick Bookstaber

``There is a general view that one way or another the end result of all the high frequency and algorithmic trading will be a blowup. But I don't think the risk is as big as many are making it out to be...the risk of a cataclysm is constrained by the lack of feedback and lack of tight coupling...As the field gets increasingly crowded, market impact will rise and opportunities will diminish'' First, let me point out the difference between high frequency trading and algorithmic trading. Both execute using computers, and since computers work really fast, both can be accused of whatever sins are embodied in millisecond trading. High frequency trading is a type of proprietary trading. The trader (or his computer) sees a profit opportunity and trades accordingly. This profit opportunity...
