Feeds and staleness
Staleness checks and stale UI states for Thesalink.
Equity feeds pause off-hours. Every read needs a staleness check.
Rule
Check updatedAt against a per-feed max age on every read. If the check fails, mark the row stale and do not show a fresh price or a fresh total.
if (block.timestamp - updatedAt > maxAge) {
state = STALE;
price = none; // show badge, not a number
} else {
state = FRESH;
value = raw * price / 1e8;
}UI states
- Fresh: price, value, and timestamp shown.
- Stale: badge shown, price blanked, row excluded from fresh totals.
- Basket stale: shown when any constituent is stale.
Off-hours
About half of stock token trades happen when equity feeds are closed. Treat every off-hours view as stale until the feed updates.
