Volatility Ratio

The Volatility Ratio was developed by Jack D. Schwager to identify trading range and signal potential breakouts. The volatility ratio is defined as the current day's true range divided by the true range over a certain number of days N (i.e. N periods). The following formula is used to calculate the volatility ratio:

Volatility Ratio (VR) = Today's True Range/True Range over N number of days

To calculate the volatility ratio, the true range is calculated using the following formula:

Today's True Range = MAX (today's high, yesterday's close) - MIN (today's low, yesterday's close)


True Range over N number of days= MAX (Day1 High, Day 2 High, ...Day N High, Day 0 Close) minus MIN(Day1 Low, Day 2 Low, ...Day N Low, Day 0 Close)

For example, the volatility ratio for a stock with a true range of 1.5 and a true range over the last 10 days of 3.5 would be 1.5/3.5 = 0.428. This volatility ratio is bordering on significant. No rules or numbers are set in stone, but a volatility ratio higher than 0.5 will generally signify to some traders that a reversal is likely.

How to Use Volatility Ratio

The use of a volatility ratio helps to identify situations where the price of a stock has moved out of its true range and may signal possible reversal days in the near future.

The volatility ratio identifies for traders time periods when price has exceeded its most recent price range to an extent significant enough to constitute a breakout. Precise readings that indicate a breakout are usually adapted by traders to the specific stock or market they are trading, but a commonly used reading is 0.5. This level represents the point at which the current true range is equal to twice the previous true range. To confirm breakout signals given by the volatility ratio indicator, traders often use other technical indicators such as volume, since trading volume generally increases sharply during market breakouts.

Отличный индюк. Индикатор применяю по своей собственной системе с элементами стратегии. Система не имеет ничего общего с авторской.

Version 1.10 2019.03.19
We addressed some issues with the previous version. There has been complain about the alert. Though the alert options are on the input menu yet it isn't giving out alerts. The free version isn't built with alerts thus we have removed it from the input menu
