This isn't an exchange feed. Real-time market data means paying a provider, so what you're seeing is
yfinance's usual delayed quotes. The server re-polls them every
20s during market hours and pushes updates straight to
this page over Server-Sent Events, which makes it feel live even though the quotes behind
it aren't. Delayed data, and not financial advice.
Market is closed. Live updates run Mon–Fri, 9:30am–4:00pm ET (a plain hours check,
not a real trading-holiday calendar). Showing the last known prices below, if any.
