What Causes Volatility?

  • Economic news releases (NFP, CPI, rate decisions)
  • Geopolitical events (wars, elections)
  • Market sentiment shifts
  • Session overlaps (London + New York)

Key Points

  • Higher volatility = wider stops needed
  • Adjust position size for volatility
  • Use ATR to quantify volatility objectively
  • Trade during high volatility for bigger moves
  • Reduce exposure during uncertain periods
