Nanex ~ 01-Oct-2013 ~ 3.5 Years of eMini Liquidity

The following chart shows the total number of contracts in all 10 depth of book levels averaged over each minute of the day (9:30 to 16:00 ET) between March 2010 (dark purple) and October 1, 2013 (bright thick red). Older days colored towards the violet end of the spectrum, while more recent days colored towards the red end. Liquidity has never recovered to former levels, probably due to increased asymmetry in the trading speed of participants: for example, faster communication (fiber to microwave) between Chicago and New York.
