➊ Annual Percentage Yield (APY)

- Applicable when:

Portfolio interest is calculated with compound interest - Formula:

Pincipal * (1 + APY%) ^ (Days of running/365) - Principal = Interest (Return) - Example:

Portfolio A whose days of running are six months and with 15% of APY

Principal: 1000 USDT

Estimated Interest: 1000 * (1 + 15%) ^ (183/365) - 1000 = 72.585861 USDT - Note:
- Days of the contract period are calculated as of the date of launch. For example, if the portfolio launch on February 1 whose contract period is solid 3 months, the actual days of running are 28 + 31 + 30 = 89.
- APY is settled on an hourly basis.

➋ Return on Investment (ROI)

- Applicable when:
