How Often Is the Mark Price Typically Updated by the Exchange?

The Mark Price is typically updated very frequently, often every second or even more often, to reflect the real-time changes in the underlying Index Price and the Funding Rate. For perpetual futures, the Index Price component is usually a moving average of multiple spot exchanges, which is updated continuously.

This constant updating ensures that the Mark Price remains a fair representation of the contract's true value, minimizing liquidation risk from stale data.
