Scheduler — keeps prices updating when a source runs out of credits, fails, or this tab is in the background

Keep the chart price currentChecks every 5 s, even in a background tab. If the price on your chart (or a pop-out chart) goes stale, it tries every source in your priority order — skipping any with no key, no credits or a pause — then Stooq as a last resort, backing off after failures.

How it connects

The page asks each site directly. If a browser blocks that (CORS), it retries through your SQL API server, which relays only these three sites. These are unofficial, unauthenticated endpoints, so they can change or rate-limit without notice; prices may be delayed. Your API key (if any) always wins for the tickers it covers.
