FAQ
How is the funding fee calculated?
Fee = notional × rate, charged at every funding interval (every 1, 2, 4 or 8 hours depending on the exchange and coin). Positive rate: longs pay shorts. Negative rate: shorts pay longs.
Is funding charged on margin or on position size?
On the full notional. Leverage does not change the fee in USDT, but it multiplies it relative to your margin.
Do I pay funding if I close before the funding time?
No. Only positions open at the exact funding timestamp pay or receive it.
