The U.S. (8 AM - 4 PM ET) and EU - U.S. overlap (3 AM - 8 AM ET) hours are critical. High institutional participation during these times drives 60% of daily volume. U.S. hours see ETF flows, regulatory news, and whale activity—key for trend direction. EU - U.S. overlap brings cross - market arbitrage and retail - institutional mix, amplifying volatility. Asian hours (9 PM - 3 AM ET) have lower volume, so moves here rarely set long - term trends unless supported by major news.
