What is Volatility?
Volatility measures how much price moves. High volatility means larger, faster moves. Low volatility means smaller, slower moves. Understanding volatility helps set realistic targets and stops.
Measuring Volatility

Volatility Factors
- Economic News: NFP, rate decisions spike volatility.
- Session: London-NY most volatile, Asian quieter.
- Currency Pair: Exotics more volatile than majors.

Trading Volatility

Adjusting for Volatility
ATR-Based Position Sizing:
If ATR = 100 pips and you risk 1%: Stop at 1.5 × ATR = 150 pips. Size position so 150 pip loss = 1% of account.
