Extended-Hours Liquidity Warning

Extended-hours trading — pre-market and after-hours — comes with real liquidity risk that's easy to underestimate: wider spreads, fewer participants, bigger price gaps. This extension gives you two things in one glance: a live clock showing exactly what session you're in right now, and a quick spread-risk check before you place an order. Features: Live, ticking session clock (Pre-Market / Regular Hours / After-Hours / Closed) based on real US Eastern Time Instant bid-ask spread risk calculation — dollar and percentage Context-aware warnings that change based on the actual current session Pro: customize your own risk thresholds, save a history of past checks Honest note: the session clock is time-based only — it doesn't yet account for market holidays or early-close days. On those days, treat the session label as informational, not a substitute for checking an actual market calendar.
