📋Perpetual Specifications

Perpetuals are a derivative akin to a future, except without an expiration. A funding rate mechanism helps keep perpetual futures prices close to the spot price of the underlying asset, see Funding and Pricing.

100x margins perps within the cross margin framework, where perps are assigned a quote asset value which forms the portfolio of a given sub account. The margin value in the table belows refers to the margin factor of an individual perp, but the margin of a perp can be improved if it is a component of a spread, meaning it is a short perp position completely offset by a long spot position.
