Compares the current candle's range to the average range of recent candles. A sudden rise in this ratio is often seen alongside a break of important levels.
How to read the chart
A rising reading means market volatility has increased and the risk of sharp swings has gone up, while a falling reading signals relative market calm.
Practical tip
