Volatility describes the magnitude and speed of price movement over a period. It is frequently confused with risk, but the two are distinct: volatility is a property of the market, while risk is the exposure a trader chooses to take within it. Reading volatility correctly is one of the most practical skills in trading, and it changes how every other technique is applied.
Measuring Volatility
Realised volatility looks backwards at how much price actually moved; implied volatility looks forwards at what option markets expect. On a chart, average true range is the common proxy, expressing the typical range of a bar in price terms. Sizing positions in ATR multiples rather than fixed distances adapts a strategy automatically as conditions change.
- Realised volatility: historical dispersion of returns
- Implied volatility: forward expectation priced by options
- ATR: practical, chart-level range measure
Regimes: Compression and Expansion
Markets alternate between compression, where ranges narrow and participants wait, and expansion, where ranges widen and direction resolves. Breakout methods depend on expansion; mean reversion depends on compression. Applying the wrong family to the wrong regime is a structural error, not bad luck.
Event-Driven Volatility
Scheduled events — central bank decisions, inflation releases, earnings — produce predictable spikes in volatility and unpredictable direction. Spreads widen, slippage increases and stop behaviour changes. Many structured traders reduce or flatten exposure around these windows rather than attempt to trade them.
Adapting Exposure
The practical response to rising volatility is a smaller position with the same risk in currency terms, not the same position with a wider stop. Platform tooling that displays volatility-adjusted sizing helps; this is one of the features we document in our independent analysis of NV-Group.
Conclusion
Measure volatility, identify the regime, and let position size absorb the difference. That single habit removes a large share of avoidable losses. Read the detailed analysis of NV-Group next, or revisit our guide to risk management in trading.
