What is the difference between position-by-position leveraged trading and full position leveraged tr

The BiyaPay Spot Leverage feature currently supports full position leverage trading and may support position-by-position leverage trading in the future. Margin in leveraged position-by-position trading mode is independent for each trading pair:
Each trading pair has a separate position-by-position leverage account. Only specific cryptocurrencies can be transferred, held and debited in a specific position-by-position leveraged account. For example, in a BTC/USDT position-by-position account, only BTC and USDT are available. You can open multiple position-by-position accounts for trading different currency pairs;
Positions are separate for each pair. If margin needs to be added, it will not be added automatically, even if you have sufficient equity in your other position-by-position or full position accounts. You will need to add it manually;
Margin rates are only calculated in each position-by-account account based on the assets and liabilities of that currency pair;
Risk is segregated in each position-by-position account. Once liquidation occurs, it will not affect other position-by-position positions.
In the Full Position leveraged trading model, the user shares margin for all pairs:
Each user can have only one Full Position account in which all trading pairs can be traded;
The equity in the account is shared by all positions;
The margin rate is calculated based on the total asset value and liabilities of the full position account;
The system will check the margin level of the full position account and notify the user to provide additional margin or close the head; once liquidation occurs, all positions will be liquidated.
