ATR%
A useful measure of recent volatility. I use 50 day or 50 week periods, but you can experiment with other values too. Because it measures ranges as a % of current close it can be used to make good comparisons with other historic periods of low (or high) volatility. This measure reached a new 23 year low for daily S&P 500 in July 2017.
