Margin
Currently, users’ trading accounts support only $BITU as the asset, which is linked to a unified margin and risk monitoring system.
The account margin is denominated in $BITU.
The margin currency’s equity (the value of the held currency) is converted into margin value based on a discount rate.
Margin Currency and Discount Rate: BitU sets the discount rate for each currency. The discount rate determines the effective value of the currency when converted into margin.
Valid Margin
Valid Margin = Total Margin Value - Margin Loss
It measures the level of risk the account can bear. A higher Valid Margin allows for more positions and liabilities to be supported.
Total Margin Value is the weighted sum of the equity and the discount rate of each currency.
Margin Loss: This includes estimated fees and potential price slippage from pending orders and positions.
Available Margin
Available Margin = Valid Margin - Frozen Margin
It is used to validate the ability to open contracts and borrow. When Available Margin is 0, there is no margin support for opening positions or borrowing.
Frozen Margin: Includes liabilities, occupied margin for positions, and reserved margin for orders.
Maintenance Margin Ratio (UNIMMR)
UNIMMR = Valid Margin / Maintenance Margin
It is used to monitor account risk.
The higher the ratio, the safer the account. If the value drops below 100%, it triggers the liquidation process.
Maintenance Margin (MM) includes liabilities and contract maintenance margin, determined by the maintenance margin rate of the risk tier.
