On unisearch, it would be useful to have ATR as a parameter; also price/ATR.
ATR is an excellent measure of a stock's volatility. If the ATR is exceptionally high, or high relative to the stock price, the stock will be untradeable. Therefore, it would be useful to be able to screen out such stocks.

The only thing I disagree with here is it should be ATR/Actual Price, not Price/ATR. The former gives the equivalent of a percentage that enables stock to stock comparison for volatility and an easy conversion to a 1X, 2X or 3X trailing stop. More specifically, too, it needs to be a parameter in both graph layout as well as search parameters.
