This question might have rose in your mind too, that why VIX was lower than yesterday despite the huge selloff today.
This is what I think happens . A thread.
What is VIX ?

What is IV ( implied volatility ) ?
Now my explanations. IV is simply demand and supply. IV is back calculated from option prices and not given by the BSM model. When demand for options ( by buyers) are high, IVs will be high. When supply of options ( by sellers) are high, IV will be low.
Now look at this chart. Nifty fut and VIX are plotted together ( red line is the VIX). Yesterday's massive breakdown forced traders to hedge their positions by buying puts ( could be cash holdings, could be future longs, could be sold puts). This excess demand spiked up IVs /VIX

Study this thread and then check the VIX charts and Nifty charts from 1st Oct 2018. There is a reason I am retweeting this now :)
1. IV > HV

2. High IVR
3. Sell strangles 2SD away
This is the crux of all complicated option selling strategies . Nothing so simple can work across all market conditions .
