What is Auto Earn in Trading Account?

Auto Earn in Trading Account is a value-added service within trading accounts that allows users to deposit their crypto assets to earn market-based interest on an hourly basis. This feature let you earn interest by automatically lending out your funds if your equity is positive. You can still use those funds as collateral and margin.

Basic Rules:

  • Use of assets: crypto assets from Auto Earn in Trading Accounts will be loaned to margin traders and flexible loan borrowers.

  • Supported account levels: VIP 1 to VIP 8

  • Supported account modes: Spot Account Mode, Futures Account Mode, Multi-Currency Margin Mode, Portfolio Margin Mode

  • Supported currencies: Currently only USDT is supported; more currencies may be added in the future

  • Master account auto earn limit: 1,000,000 USDT

Switch on and switch off

1. Switch on

By default, Trading Account Auto Earn is not enabled in users’ accounts. Users can switch on Auto Earn in trading accounts at any time as long as there is positive equity in users' trading accounts. Following switching on, their crypto assets will participate in interest rate bidding together with the crypto assets locked in Simple Earn. Crypto assets will be lent to margin traders if a bid is successful.

2. Switch off

You can turn off Auto-earn at any time after it’s been on for at least 24 hours, regardless of whether your funds have been lent out. Note that while Auto-earn is on, you can’t transfer or withdraw funds eligible for auto earn.

Quota Rules

The individual earning quota for Auto Earn in trading accounts is set at the main account level and is shared among main and sub-accounts. OKX may, at its sole discretion, adjust the individual subscription and redemption limits for Auto Earn in trading accounts, as well as the total Auto Earn limit for trading accounts, based on actual market conditions and risk levels.

The total amount users can use for subscription is determined by the user's cryptocurrency equity and the remaining available earning quota. The allocation of earning quotas between accounts follows the order from low to high annual lending rates, and from early to late in terms of when Auto Earn was activated.

Interest rate setting and interest distribution

1. Interest rate setting

For Auto Earn in trading accounts, you can set your minimum lending APR when subscribing and this can also be revised anytime on the order details page. Your main account’s lending quota is shared across your main account and sub-accounts. It’s first allocated based on each account’s minimum lending APR (from lowest to highest), and then by the order in which you turn on Auto-earn for each account (from earliest to latest). Note that each account’s available quota may change in real time based on the quota usage of your other accounts.

Auto Earn in trading accounts approves loans based on the following rules:

  • If your minimum lending APR is lower than the market APR, your funds will be loaned at the market APR.

  • If your minimum lending APR is equal to the market APR, your funds may either be partially loaned or not loaned at all.

  • If your minimum lending APR is higher than the market APR, your funds will not be loaned at all for that hour, and you will not receive any interest.

There is an exception to the foregoing rules: if the supply of all available lender's funds is almost fully loaned out, the market APR may be raised to attract more lenders. In such situations, notwithstanding that your minimum lending APR may have fallen below the new market APR, there is a possibility that your funds might not be loaned out, which could result in no interest earnings.

If the minimum APR of multiple lenders is equal to the market APR, loans will be approved on a first-come, first-served basis.

2. Interest calculation and distribution

For users whose lending offers are successfully matched on the hour T, the hourly interest for the corresponding loan amount from T to T+1 will be distributed on the hour T+1.

15% of the interest will be deposited as margin and 85% will be distributed to trading account auto earn users. 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. The remaining outstanding loss will be temporarily covered by the platform and this amount will be gradually deducted from margin and daily interest in the future.
