FAQ

Which global indices does TickDB cover?
US (S&P 500, NASDAQ, DJIA), Asia-Pacific (Hang Seng, SSE, SZSE, Nikkei), European (DAX, FTSE 100, CAC 40), and other major global indices.
Is index data real-time?
Yes. Real-time index data is streamed via WebSocket with continuous updates during trading sessions.
Does TickDB provide index constituent data?
Individual stock quotes for index constituents can be accessed through the corresponding market APIs (US stocks, HK stocks, A-shares). Index constituent lists are not yet available but are planned for a future release.
Does the free plan include index data?
Yes. The free plan includes real-time data for select major indices with push frequency limits. Upgrade to unlock all indices and higher push frequencies.
Yahoo Finance already has free index data — why use TickDB?
Consider Massive for index streams, Nasdaq Data Link for dataset procurement and Twelve Data for multi-asset queries. TickDB suits cross-market monitoring. Yahoo Finance remains an additional viewing option, not an equivalent index feed.
