Strategy formulas for both crypto-margined and USDT-margined contractsFunding Rate ArbCrypto-M and USDT-M Formula APR = (P3D perpetual funding / 3) × 365 Explanation P3D perpetual funding refers to the previous 3-day historical perpetual funding rate. This formula annualizes the previous 3-day historical perpetual funding rate to provide a comparable APR value.

Your weekly reward = (Sum of daily lowest hourly snapshot balances) × (Current APR / 365) × (Number of days you held USDG that week). Example: If you purchase USDG on day 1 and your previous balance was 0, then your lowest hourly snapshot balance for that day is 0. If you hold USDG for only 3 days in a given week, you will receive rewards for those 3 days on the following Wednesday.

Your hourly reward = Hourly reward tokens × Your staking amount in the previous hour × Your Bonus Multiplier ÷ Total weighted staking amount of all users Your hourly APR = (Your hourly reward × Reward token price) ÷ (Your average hourly staking amount × Staked asset price) × 24 × 365 Note: the APR displayed on the page is for reference only. Actual returns may vary depending on market conditions and final reward distribution. How is my hourly staking amount calculated?

Actual interest = Actual loan amount * Current APR/365/24 * 85%.Source and use of margin 15% of the interest paid by margin traders will be deposited as margin to cover potential losses. OKX reserves the right to use the 15% interest for other purposes.In the event that the margin cannot cover potential losses, a maximum of 50% of the relevant users' daily interest will be appropriated to cover the outstanding loss so as to ensure users receive interest every day.

Interest calculation: Interest = Liability exceeding the interest-free quota × (Annualized interest rate / 365 / 24) Liability exceeding the interest-free quota and annualized interest rate are both recorded at the start of every hour. Note that liability exceeding the interest-free quota incurred in the first minute of the start of every hour might be recorded as well. Example: If you have a liability incurred at 22:50, no interest will be deducted at this time.
