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...
