Definition
The Volatility Ratio is a technical measure used in financial analysis to assess relative changes in the price movements of a security. It helps traders identify potential trading opportunities often manifested as breakouts or price patterns. The ratio typically involves the comparison of the current true range (the difference between the highest and lowest prices over a specified period) with the average true range over a longer term.
| Volatility Ratio |
Average True Range (ATR) |
| Measures price movements relative to the recent past |

| Useful for identifying potential breakouts |
Helps traders gauge overall market strength |
| Can be adjusted for different timeframes |

Example
The most common calculation of the Volatility Ratio involves computing:
\[ \text{Volatility Ratio} = \frac{\text{Current True Range}}{\text{Average True Range}} \]
-
True Range (TR): The greatest of the following:
- Current High - Current Low
- Current High - Previous Close
- Current Low - Previous Close
-
Average True Range (ATR): A technical indicator that measures market volatility by decomposing the entire range of an asset for that period. It’s calculated as the average of the True Ranges over a certain number of periods.
