Volatility Ranker: stocks that swing back and forth

Swing traders look for stocks that move up and down often enough to trade both ways. The Volatility Ranker scores every U.S. and Canadian stock from 0 to 100 on how often its closes switch between peaks and valleys over the last 14, 30, 90, 180 or 365 days, with the low and high of that period.

A high score means many swings; a low score means the stock mostly moves in one direction. Stocks with a price gap in the period are left out, so one jump doesn't skew the score.

Questions

How is the volatility score calculated?

It counts the peaks and valleys in the closes over the period: the more often the stock turns, the higher the score, up to 100.

Is a high score good or bad?

Neither. Swing traders look for high scores; investors who want steady trends may prefer low ones.

Why is a stock missing from the list?

Stocks with a price gap in the period, or with fewer than 5 sessions of data, aren't scored.

How often is it updated?

Every trading day, overnight after the close.
