Prices, company filings, earnings dates and news all come from outside data providers. The app uses more than one, and falls back from the main provider to a second when the day's allowance runs out. That is why a figure can be present in the morning and missing in the afternoon, or slightly different between two screens.
23.1 Freshness and caching
Some boards are shared. The first person to open a heatmap or a sector view pulls the data and everybody else reads the same capture — which is why the page shows a timestamp and says whether you are looking at a shared board or a live pull. ⟳ Update data forces a fresh one.
Some things are only computed while the app is open in a browser tab:
- price alerts — at launch and every five minutes;
- pending limit and stop orders — every five minutes, and when you open the Portfolio page;
- the feed (75 seconds), messages (20 seconds), channels (30 seconds).
Close every tab and none of that happens.
23.2 When data is approximate, or absent
Wherever the app is showing you something less solid than it looks, it says so on the page rather than in a footnote here. The recurring cases:
- Index membership
- The heatmap boards are hand-picked large caps, and the earnings “leading companies” filter is heavily traded US stocks. Neither is a licensed index constituent list — no provider on these plans sells one.
- Approximated sector figures
- Where a sector number had to be built from its constituents rather than read from a sector endpoint, the page notes it underneath.
- Missing earnings history
- Older months can come back empty. The page reports how many of the months you asked for were actually covered.
- Symbols with no price
- Shown as NA or Pending rather than dropped, so a position you own never quietly disappears.
- Provider out of allowance
- Some panels — trending movers in particular — say when they have fallen back to a derived ranking from the last completed session instead of the live list.
