Live crypto and futures prices

Directly from LBank's public WebSocket. One relay process on our server holds the upstream connection, coalesces ticks every 250 ms and forwards them to your browser. No price is estimated or substituted from another source.

Because "unknown" and "zero" are different facts. If the exchange has not published a 24h high, low or turnover for an instrument — or the instrument has not traded in 24 hours — we render a dash. Writing zero there would assert something we do not know.

The exchange does not send a percentage. It sends the last price and the 24h-ago open, and we compute (last − open) / open × 100 from those two numbers. When the open is missing the percentage cannot be derived and the cell shows a dash.

The badge above the table turns red and reads "Prices are not up to date", and the table renders an explicit no-data state instead of numbers. We do not keep serving the last value we held as though it were live — a stale number that looks current is worse than no number.

Only the ticks this browser has received since you opened the page. It is not a 24-hour chart and we add no synthetic points to it; until two real ticks have arrived you see "not enough data" rather than a line.

Every USDT perpetual LBank publishes in its SwapU product group — 833 instruments in the latest snapshot, crypto plus tokenised commodity and equity instruments. The live count is shown above the table.
