Frequently Asked Questions
What is compound funding in crypto trading?
Compound funding means reinvesting your perpetual futures funding income back into the position each interval, so subsequent earnings are calculated on a larger base. Instead of withdrawing funding payments, you let them compound — similar to compound interest — which accelerates capital growth over time.
How is annualized APY calculated?
APY = (Final Capital / Initial Capital)^(365 / Days) − 1. This accounts for the compounding effect of reinvesting earnings each interval. A 0.01% funding rate per 8h with 100% reinvestment over 30 days yields roughly 13.5% APY.
What does reinvest percentage mean?
At 100%, every funding payment is added back to your capital immediately, giving full compounding. At 0%, you withdraw all earnings and growth is purely linear. At 50%, you keep half and reinvest half — giving partial compounding. Lower reinvestment rates reduce APY but free up cash.
What is a realistic funding rate to use?
Long-term average funding rates on BTC and ETH perpetuals range from 0.005% to 0.03% per 8h depending on market sentiment. During bull markets rates can spike to 0.1%+. For conservative projections use 0.01% per 8h. For bear markets, rates can go negative — shorts pay longs.
