**1. What is Savings?**

Savings is our value-added product for flexible earnings. You can earn hourly interest, as well as deposit and withdraw your assets at any time. Regardless of the borrowing demand, you can get the highest interest rate. Hourly interest helps you to use your funds with the maximum efficiency. And you can earn even more with increased limits if you invest large amounts. Assets from Savings are used to fund OKEx margin loans.

**2. What’s the difference between simple and advanced modes?**

We’ll automatically set the current highest APY in simple mode for you. You can set the min. APY in advanced mode. If min. APY equals or is lower than current APY, your funds will be loaned based on the current APY. If min. APY exceeds current APY, your funds won’t be loaned at all.

**3. How APY is calculated?**

The market will bid hourly starting from the lowest APY according to the current demand. The highest value will be considered the current APY.

- If min. APY is lower than current APY, your funds will be loaned based on the current APY.
- If min. APY exceeds current APY, your funds won’t be loaned and you won’t get any interest.
- If min. APY equals current APY, your funds will be partially loaned or won’t be loaned at all.

**4. What’s the est. APY in simple and advanced modes?**

In simple mode, we use APY for the last hour as the reference, and update it every hour. In advanced mode, we analyze queue and lending amounts every minute, and use the matched APY as the estimated APY for the next hour.

**5. Do I need to set min. APY for every hour in advanced mode?**

You can set min. APY hourly, but there’s a chance your loan won’t be completed due to market volatility. If you don't set min. APY for the next hour, our system will use min. APY you set for the previous hour.

**6. How hourly interest is calculated?**

Hourly interest equals the lending amount multiplied by current hourly APY (yearly APY divided by 365 and divided by 24). Note that you get 85% of the interest because 15% goes to OKEx insurance fund.

**7. What’s the difference between redemption time and arrival time?**

Redemption time is the moment when you requested to redeem your funds. Arrival time will be within the next hour after redemption time.

**8. Why redeemed funds didn’t arrive in real time?**

Assets from Savings are matched hourly and used to fund OKEx margin loans. Lending cycles also last one hour, so you can get your funds back in one hour after lending, not earlier. For example, Alice deposits 1,000 USDT at 15:10 and her funds are used to fund a margin loan at 16:00. The lending cycle will last from 16:00 to 17:00. If Alice requests to redeem her funds at 16:05, she’ll be able to get them not earlier than 17:00.

**9. Why are my total earnings blank?**

Total earnings include all the interest of your subscription. Once you redeem funds, you won’t see them under Total earnings. This amount can also be blank if your funds aren’t successfully loaned.
