What is volatility targeting and dynamic leverage in forex?

Volatility targeting sizes positions so your realized portfolio volatility stays near a target (say 10% annualized). If markets get quiet, position sizes scale up; if turbulence rises, sizes shrink—stabilizing the equity curve. Implementation: compute rolling realized vol (e.g., 20-day ATR or standard deviation), translate to annualized vol, then set position size = (Target Vol / Realized Vol) × Base Size, often with caps to avoid oversized leverage in ultra-calm regimes. Example: EUR/USD realized vol drops from 9% to 6%; to maintain a 10% target, exposure increases by ~67%—subject to max leverage and liquidity checks. Pros: drawdown control, comparability across assets, and cleaner risk-adjusted returns. Cons: whipsaw risk when vol spikes, lagging estimates, and potential underperformance in fast trends. Best practices: apply floors/ceilings (e.g., 0.6×–1.6× multipliers), blend multiple vol horizons (10/20/60-day) to reduce noise, and combine with event filters (reduce 30–50% size around central bank days). Volatility targeting works well with diversified systems, converting uneven market risk into a consistent experience.
