Session timing matters considerably more in forex than most beginners realize. Volatility and liquidity vary dramatically across sessions. The London session typically produces the most consistent trending moves for major pairs involving European currencies. The New York session overlap with London, roughly four hours, generates the highest volume and sharpest price action of the trading day. Asian session hours tend toward range-bound behavior with lower volatility for most major pairs. Matching your strategy type to appropriate session characteristics significantly improves its effectiveness.
