My watchlist

No. Your list is stored in this browser (localStorage) and works with no account and no email. If you want the same list on another device you can optionally link it to the Telegram account that has already started the TradeYar bot. Until you do, no copy of your list exists on our servers.

Because the user portal's session cookie is issued only on the portal's own hostname and never reaches the API host this page talks to, so a 'sign in' button here would not have worked — and we would rather not ship a button that does not work. Instead we use an identity that can actually be proved: a six-digit code is sent to that Telegram chat, and nothing is linked to your account until you type it back.

The server keeps a revision number per list. If the second device tries to write over a revision that is no longer current, the write is refused and the server's current list is handed back to that device; the two are then merged and the result is saved. The rule is the union of the two lists, not replacement — an extra symbol is a better failure than a lost list.

Prices come from the LBank exchange WebSocket, batched every 250 ms. If the live connection cannot be established the browser falls back to reading REST every 15 seconds, and the page labels which tier it is on. If no data arrives at all, the page says the prices are not up to date instead of showing a stale number.

A dash means that value is unavailable — it does not mean zero. Two quite different situations produce it, and the feed-status badge above the table tells you which one you are in. While the feed is connected, a dash means the exchange sent no number for that instrument in that column. If the badge says prices are not up to date, the dash says nothing about the instrument itself; it only means the data could not be read just now. In neither case do we print a stale, zero or guessed number.

Yes. The server-side storage service is answering right now and the cross-device sync panel below the table is active.
