Themis' Take: May 6, 2010 -- The Day That Will Change Market Structure

...The story is not a key-punch error. The story is a failed market structure. The market failed today. The market melted down and ``liquidity providers'' quickly pulled all bids. According to today's Wall Street Journal, high frequency firm, Tradebot, closed down its computer systems completely, as did New Jersey's own Tradeworx,...To make matters worse, while some high frequency firms shut down yesterday and pulled their bids, as we warned they would do for over a year and a half, other high frequency firms turned from being liquidity providers to liquidity demanders, as they turned around and indiscriminately hit bids...The market action of May 6th has demonstrated that our equity market has major systemic risks built into it...The price discovery process ceased to exist. High frequency firms have always insisted that their mini-scalping activities stabilized markets and provided liquidity, and on May 6th they just shut down. They pulled the plug, as we always said they would, and they even admit it in the papers this morning...This is not an isolated incident, and it will happen again.
