For ordinary orders, if non-USDT assets are used as the order margin (on hold/in frozen state), and when the asset is affected by the market capitalization change and the account assets cannot meet the margin call, all orders will be canceled by default. It should be noted here that frozen assets are no longer a fixed amount of digital assets, but digital assets with a fixed market capitalization.
Suppose you place an order worth 10,000 USDT and select the 100x leverage, ignoring the changes in the underlying market, there is only 0.01 BTC in the account.
At time A, when the exchange rate (index price) of BTC is 10,000 USDT, the market capitalization of the frozen margin is 100 USDT.
At time B, when the market capitalization of BTC lowers to 9,999 USDT, and the market capitalization of 0.01 BTC drops to 99.99 USDT. The contract value of the buy order remains unchanged at 10,000 USDT. At this time, the account assets can no longer meet the requirement of the margin with a market capitalization of 100 USDT, then the order will be canceled in full.
