Close this dialog, search a card, and add it. Set a price threshold on each card (or a notification price filter via the ⚙️ beside the bulk-threshold bar) and you'll get a Telegram alert when it drops below that price on CardTrader Zero.
Scan every tracked card right now and send a per-card report to Telegram — shows which cards have CT Zero listings, which don't, and any errors. Use this if alerts seem quiet or a price looks stuck.
Each code admits exactly one new Google account, then is used up.
Download every user's watchlist & price history before a redeploy, then restore it after.
Delete every recorded price point before a chosen date & time, across all users. Use this when an old ↓ below avg reading is being skewed by stale data left over from before a redeploy — the average is computed over all stored points, and history isn't cleared when a card is removed and re-added.
Confirms your data sits on a persistent volume and won't be wiped on the next deploy.

Mute trivial price wobble. For each price tier, set how much a card's price must move (in €) before you get another Telegram alert. Example: a 50€ card moving 30¢ isn't worth a ping, but a 1€ card moving 30¢ is. Up to 5 tiers · leave a Min or Max blank for “no limit”.
Track cards on CardTrader Zero and get a Telegram message the moment one drops below the price you set.
Paste a decklist and scan for CT Zero deals.
Cards below your threshold are highlighted.
