Good article here about active/passive investing and the thread of robots breaking the market. There is a good description of “gamma traps” and liquidity around options gamma.

Review of Flash Crash of May 6, 2010
Some liquidity notes from SEC review of the “Flash Crash” of 6/10/2010. Day started off with video of riots in Athens. Market was down a few percent and VIX was up.

Here is a chart estimating the futures action with the S&P500 at 2850. If markets head lower it looks like dealers will sell more futures, compounding the move down.
