Real-time quotes streamed for every symbol you track — the live data spine of the whole terminal.
Helius Terminal streams real-time bid, ask, last price, size, and volume for all your positions and watchlist symbols at once. This live feed powers every other feature in the terminal — the prediction model, alerting, P&L tracking, and AI analysis all run off the same real-time stream.
What this feature does for you
Bid, ask, last price, bid size, ask size, and volume streamed live for every symbol in your watchlist and positions — updated on every market tick.
The terminal computes microprice (size-weighted fair value) from live bid/ask/size data — a more accurate estimate of true market value than raw last price.
All positions and watchlist symbols are streamed over a single live connection. Adding or removing symbols updates the stream instantly without reconnecting.
The live stream is the data spine of the terminal. The prediction model, alerting service, portfolio P&L, and trade execution all consume this same real-time feed.
If the live connection drops, the terminal automatically reconnects and resubscribes to all active symbols — no manual action required.
The terminal is aware of pre-market, regular session, and after-hours trading. Data continues to stream during extended hours where your broker provides it.
