Where prices come from
Prices come from market data sources covering US and international stocks, ETFs, mutual funds, and crypto. Availability and delay vary by security and by exchange.
Prices are fetched when a page loads and cached for up to five minutes. Every portfolio and watchlist view carries a "Prices last fetched" stamp showing the oldest of those retrieval times.
That stamp says when we last fetched a price, which is not the same as the moment the quote itself measures: a feed can return an earlier close. We are working on carrying the market timestamp through so the two can be told apart.
When a current price cannot be retrieved, we show the last price we hold, marked delayed, rather than substituting a different figure. A delayed price never triggers a price alert.
Company financial statements are a separate matter: those come from SEC filings and are described in Where the numbers come from.
