Contract mechanics

What it tracks: SoftBank Group — equities. This is a perpetual contract that references that price; it is not the underlying security, and it never expires or rolls.
Trading hours: Follows the listing exchange of the share it references: trading days only, closed at weekends and on that exchange’s holidays, extended by an overnight session where the deployer prices one. The contract itself trades on Hyperliquid 24/7.
When the real market is closed: The oracle does not freeze. With no external price it starts from the last one and then drifts with Hyperliquid’s own book — a 30-minute exponential average of the gap between the impact bid/ask and the oracle — and snaps back to the real price on the first tick after the market reopens. Funding is charged against that oracle throughout, which is why the jump at each reopening is worth measuring.
Leverage: Up to 10×
Margin mode: Isolated only
Settles in: USDC — margin and profit are in this token, not the quote of the underlying market.
