Tessen Market Clock — New Tab

About

⏱ CANDLE CLOSES — live countdowns to the next 15m, 1H, 4H, daily, weekly and monthly candle close, UTC-aligned exactly like Binance, Bybit, OKX and TradingView. If your strategy acts on closed candles, this is the clock it runs on.

💸 FUNDING TIMERS — the next funding payment on the standard 8h grid (00/08/16 UTC used by Binance, Bybit, OKX and Bitget) and the hourly venues (Hyperliquid, Coinbase INTX). Hold through the timestamp and you pay for the full interval — know exactly when it hits.

🌍 MARKET SESSIONS — Sydney, Tokyo, London, New York and CME crypto futures (including the daily maintenance halt), computed from each desk's local clock so daylight-saving shifts are always already applied.

The toolbar badge shows the countdown to the next 4H candle close even when the panel is closed.

No account. No sign-up. No tracking. No network requests at all — everything is computed locally from your system clock. The extension asks for no data permissions because it doesn't want any.

Built by Tessen (tessen.ai), the platform that grades trading strategies on out-of-sample data — honestly, including our own.
