This is a commonly used calculation that many traders use, I believe it's also part of the CMT.

Currently, according to the calculation we should expect a 5.8% move withing the next 30 days.

Thanks for the post. Is it the same equation for VXX?

@Shiloh777, This equation wont work to calculate the the monthly volatility because VXX is priced differently to the VIX. This is because the price of the VIX is actually the implied annualised monthly volatility of the SPX. VXX is not, it's just the futures.
