Understand Yesterday

Yesterday is a daily Bitcoin market built around one question: what if you could still make a trade around yesterday’s price?

Two people fund a Yesterday contract. One wants a conditional sale or purchase outcome. The other pays for the opposite exposure. Tomorrow’s average Bitcoin price decides how they share the money already put into that contract.

The result depends on the price and the agreed terms. Yesterday does not promise that you will receive yesterday’s price.

Five things to know

1. Yesterday’s price is a daily average. It stays fixed for the trading day.
2. Each fill has its own terms. A fill is the part of an order that actually executes.
3. Both sides pay before a contract is created. Its payout cannot exceed the assets already funded.
4. The payout uses tomorrow’s full-day average. Settlement can begin the day after tomorrow, once that average is valid.
5. Either side can lose its full contribution. A funded contract cannot be closed early.
