Exchange of USDT for USDT-M positions in multi-asset mode

This document outlines how Bitget exchanges non-USDT coins to USDT in a fast and cost-efficient manner for USDT-M positions in multi-asset mode to mitigate trading risks.

Three scenarios:

1. Switching from multi-asset mode to single-asset mode: If a user has insufficient USDT, they can exchange other coins in their USDT-M futures account for USDT.

2. Debt exceeds individual debt limit: When this occurs, risk control will be triggered, and other coins will be exchanged for USDT to repay the debt.

3. Risk of liquidation or partial liquidation: In such cases, other coins will be exchanged for USDT to repay the debt and reduce the risk.

An exchange rate will be applied during the exchange. The amount after exchange = quantity of coins exchanged × index price of the coin × exchange rate. The exchange rate is tiered, meaning the larger the amount, the lower the exchange rate.

Note: In the event of liquidation or partial liquidation, the exchange rate is determined by the exchange rate tier corresponding to the total value of the coin in the user's account.
