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 | Measures the average volatility over a specific period |
| Useful for identifying potential breakouts | Helps traders gauge overall market strength |
| Can be adjusted for different timeframes | Serves as a baseline for various trading strategies |
