Relative volatality

Hello all ,
Do anyone use an excel spread sheet or any software that calculate "Relative volatality"
as mentioned in Cristopher grafton’s book "Mastering hurst cycle analysis"
There are more than 1500 stocks traded everyday, to calculate relative volatality for all stocks individually is impractical.

Do anyone use / have any excel spreadsheet , or how do everyone calculate it for own analysis ?

Surely you can achieve it by writing a small screener script in MT4/ prorealtime/ tradingview or similar?
