Funding Calculation

More information about the funding rate is available in the Perpetuals Guide.

	Funding Base Rate	Funding Quote Rate	Premium
Symbols	ZRO	USDT	.ZROUSDTPI8H
Rates	0.03%	0.06%	0.0097%

I = Interest Rate, B = Funding Base Rate, Q = Funding Quote Rate, T = Funding Times Per Day
P = Premium Rate, F = Funding Rate

The Funding Rate is the rate exchanged between users.
The Premium Rate is used to calculate it, adjusted by the Interest Rate by up to 0.05%.

Formula

I = (Q - B) / T
F = P + Clamp(I - P, -0.05%, 0.05%)

Result

I = 0.0100%
I = (0.06% - 0.03%) / 3
F = 0.0100%
F = 0.0097% + Clamp(0.0100% - 0.0097%, -0.05%, 0.05%)
