Rounds & round browser

Crypto Up/Down markets run as back-to-back rounds — the live one, the one that just closed, the one that opens next. The round browser in the /crypto header lets you step through all of them.

The 3-across selector

Right of the Beat / Now / Exp pill, three small market cards sit side by side:

Left — the most-recent past round, with its outcome chip (▲ UP / ▼ DOWN) and its beat price.
Middle — the focused round. By default this is the LIVE round, marked with a flashing red "recording" dot.
Right — the next upcoming round, with a countdown to when it opens.

The chevrons on each side walk the whole 24h window of rounds. The center card opens a dropdown listing every round in the last day plus the next three — beat prices and outcomes shown — so you can jump anywhere instantly.

Viewing a past round

Clicking a past round in the strip (or dropdown) puts the whole chart into a read-only view of that exact round:

Probability chart rewinds to that round's UP/DOWN curve and final outcome.
Candle chart auto-scrolls to the round's time window with the round boxed and centered. Older history pages in automatically if needed.
Beat line on the candle chart switches to that round's beat price (not the live round's).
Beat / Now / Exp pill updates: Beat shows the past round's beat, Result shows the final outcome, Exp shows Ended.
Trade panel goes read-only with a banner — you can't place new orders into a round that's already settled.

Switching back to the live round (any of: click the LIVE card, click Go to live marketin the Past Markets panel, change asset, change interval) resets the chart cleanly to the live edge.

Viewing a future round

Up to three future rounds are listed. Selecting one shows a placeholder — the round hasn't opened yet, so there's no chart data — with a live countdown to when the round begins. The trade panel stays disabled (the order book isn't live yet either).

Auto-advance

When the live round ends, everything shifts forward automatically — the strip re-anchors with the previous live round becoming the most-recent past, the new live round flashing red, and the next future round sliding in on the right. If you're following the live round, the chart stays live; you don't need to refresh.

Behind the curtain

Every round is captured as a full snapshoton the server — market metadata (condition id, token ids, tick size), the round's beat price, its final outcome, and the tracked wallets that bought in. Snapshots are kept for 24 hours and auto-deleted; that's why the browser covers the last day. Loading any of those past rounds is a single DB read, not a Gamma fetch — clicking through them is instant.

Tracked-wallet markers from a past round are filtered to wallets you actually track — same list your Wallet Trackersuse — with their label, emoji and avatar attached, so the same wallets you watch live also show up on the past-round chart.
