The margin ratio is a risk measurement indicator for a currency asset in an account.
Margin ratio=(balance in the entire position of the currency+full position return - number of orders sold in the currency - number of options purchased in the currency - number of orders opened in each position - all order renewal fees)/(margin maintenance+liquidation fees).
Maintaining margin refers to the sum of four parts, including leveraged borrowing margin, delivery margin, perpetual margin, and option margin, which are considered for holding orders; The liquidation fee is the sum of four parts, including leverage borrowing fee, delivery fee, perpetual fee, and option fee, which are considered for placing orders.
This setting is to avoid a sudden change in the risk level of the account after trading orders, which may lead to the risk of account liquidation.
