Size on the Bid-Ask Already Much Lower Than Recent Years

 

Worse This Time

The liquidity diminished in after the Feb 5th meltdown worse than the Aug 2015 crash. Both had similar down moves in price and high daily volatilities, but the options market width went up 102% for the Feb '18 (vs 48% in Aug 2015) and the size on the bid ask decreased 28% in Feb (vs 18% in Aug '15).
