Funding Rate/Funding Payments
The periodic payment exchanged between long and short position holders is by default every 8 hours, but may vary by instrument (see _our contracts offering & specs _for specifics of each contract). Funding keeps the perpetual’s price tethered to the underlying’s index price. If the perpetual is trading above the index (premium), longs pay shorts; if below (discount), shorts pay longs. Traders only pay or receive funding if they hold a position at the funding timestamp.Insurance Fund
