Frequently Asked Questions
Funding Payment = Position Size × Funding Rate. For example, if you hold a $10,000 long position and the funding rate is 0.01%, you pay $1.00 (if positive, longs pay shorts). The sign depends on the rate.
A positive funding rate means longs pay shorts. This typically occurs when the perpetual price is above the spot price, indicating bullish sentiment. Shorts receive the payment.
Most exchanges apply funding every 8 hours. Some have different intervals (e.g., hourly). The rate is calculated based on the average premium between the perpetual and spot prices.
Yes, a negative funding rate means shorts pay longs. This happens when the perpetual price is below the spot, indicating bearish sentiment.
If you hold a position for several funding intervals, you will either receive or pay the funding rate each time. This can significantly impact your net profit, especially for large positions.
No, each contract has its own funding rate based on its specific market conditions. The rate is determined by the premium of the futures price over the spot price.
Yes, some traders close their positions just before the funding timestamp to avoid payment, then re-open after. However, this may incur additional trading fees and slippage.
Positive funding indicates bullish sentiment (longs dominate), negative indicates bearish (shorts dominate). Extreme funding rates can signal over-leverage and potential reversals.
