Oracle price

Oracle price is the externally sourced reference price Hyperliquid uses as the honest anchor for a market.

In short

The oracle price aggregates prices from outside the venue to represent an asset's fair value, feeding funding calculations and the mark price. It prevents on-venue price movement alone from dictating margin outcomes.

Why an external anchor exists

Without an external reference, a large enough participant could move the venue's own price and trigger liquidations against others. The oracle makes that attack far more expensive.

It also means the perp can visibly deviate from the oracle for a period — that deviation is what funding is charged on.

Questions

Frequently asked

Is oracle price the same as mark price?

No. Mark price is derived using the oracle plus venue data.

Does it affect my fills?

Not directly. Fills come from the order book; the oracle governs funding and margin.
