The funding fee charges in your Perpetual account exist to cover the costs associated with maintaining the price alignment between the spot and futures markets, as these contracts do not have a fixed delivery date.

When funding rate is positive, long position pay to short positions. When funding rate is negative, short position pay to long positions.

Funding Fee Calculation:

Position Value x Funding Rate = Funding Fee

Example: If you hold a long position of 1 lot BTCUSD at a price of $70,000, with a funding rate of 0.01%, the funding fee is calculated as follows:
70,000 USD * 1 lot * 0.01% = 7 USD

Funding rates are charged based on market conditions every 8 hours 02:00/ 10:00/ 18:00 (AEST). These rates are adjusted in real-time to align the spot and futures prices, offering transparency and ensuring the funding fee is applied accurately. To avoid these charges, traders can close their positions before the funding times.
