Volatility Ratio for Classifying High and Low Volatility Regimes

Summary

The document introduces a volatility ratio as a way to distinguish quieter market conditions from more volatile ones. It contrasts this approach with standard deviation, arguing that a ratio with a reference level can make relative volatility states easier to identify. The proposed interpretation is that readings above 1 indicate higher volatility, and the indicator is intended to describe volatility conditions rather than predict price direction.

The text recommends pairing the measure with a separate directional or trend indicator, using the ratio to check whether current volatility matches the conditions a strategy expects. It does not give the ratio’s calculation, sampling window, data requirements, or empirical examples. It also repeats the above-1 interpretation for both high and low volatility, an apparent inconsistency that leaves the lower-volatility threshold unclear. No trading results or validation are supplied, so the description is a general usage concept rather than a reproducible or tested method.

Key ideas

• The ratio is presented as a way to classify relative volatility conditions.
• The document associates values above 1 with higher volatility, but repeats that rule for lower volatility as well.
• The indicator is described as non-directional and should not be used alone to assess trend.
• A separate directional method can be paired with the ratio to check volatility suitability.
• The ratio’s formula and empirical validation are not provided.
