Regional session effects exist but are subtle due to 24/7 trading. Liquidity and volatility typically vary with major fiat-region business hours: lower depth and wider spreads often appear during local night-hours; news-driven liquidity injections occur around major economic releases in US/Europe/Asia. Institutional flows concentrate during overlapping sessions (e.g., London–NY overlap), producing tighter spreads and higher trade volume. Retail-driven activity peaks—weekends or local evenings—can amplify volatility on smaller venues. However, these patterns shift with market regime and participant mix; they are not fixed calendar rules. Use intraday liquidity heatmaps and cross-venue depth to model session-specific execution risk rather than assuming rigid time-of-day effects.
