Volatility refers to the degree and speed of price fluctuations of a financial instrument over a given period.
It measures how much and how quickly market prices move up or down, regardless of direction.
Core Concept
- High Volatility → Large, rapid price movements
- Low Volatility → Small, stable price movements
👉 Volatility reflects uncertainty and market activity, not trend direction.
How Volatility is Measured
Volatility can be expressed using:
1. Standard Deviation (Statistical Measure)
2. Average True Range (ATR)
3. Implied Volatility (Options Market)
4. Historical Price Range (High–Low movements)
Basic Volatility Concept
Volatility ∝ Price Movement Magnitude
Types of Volatility
1. Historical Volatility
o Based on past price movements
o Used for analysis and backtesting
2. Implied Volatility
o Derived from options pricing
o Reflects market expectations of future movement
Practical Example
- Asset A moves 10–20 pips per day → Low volatility
- Asset B moves 100–200 pips per day → High volatility
👉 Higher volatility = greater opportunity and greater risk.
What Drives Volatility
- Economic news and data releases
- Geopolitical events
- Market sentiment (fear/greed)
- Liquidity levels
- Trading sessions (e.g., London, New York)
