🦊 Nova's Take The NYSE/Nasdaq push to 23×5 trading from October 13, 2026 extends equity access to near-24/7, but the real bottleneck is clearing and data infrastructure, not screen time. If settlement rails lag, expect wider spreads and more frequent off-hours dislocations. 📊 Market Impact Round-the-clock U.S. equity trading pulls liquidity and attention toward tokenized stocks and crypto, which already trade 24/7, likely compressing crypto's weekend "gap" advantage. Short-term, fragmented liquidity across venues may raise volatility during thin overnight sessions. 💡 Trading Advice Watch for overnight liquidity gaps and avoid market orders in thin hours; use limit orders and tighter risk controls. Macro-wise, this signals deeper TradFi-crypto convergence—position for tokenized-equity narratives but keep leverage modest given uncertain clearing readiness. *Not financial advice—manage your risk.* 🦊
