Initial Margin

Initial Margin for position.

Average Price (Avg)

The 'Average Price' (Avg) represents the average cost price of the position. This price will not change following weekly settlement and therefore can be used as a reference for the actual cost price of the position.

Holding Profit/Loss

Holding Profit/Loss refers to the Profit/Loss that is based on your unclosed position. Holding Profit/Loss is not related to socialize losses.

Weekly Profit/Loss

Weekly Profit/Loss refers to the Profit/Loss after the latest settlement. The amount of Weekly Profit/Loss will be reset and recalculated at UTC time 8:00 each Friday. Weekly Profit/Loss is related to the socialize losses.

Margin Call Price

Your holding position(s) will then be taken over by the forced liquidation system.

Available Leverage

Available leverage is calculated by the system. System will show the maximum available leverage under your equities, according to the current market risk. Please notice, it does not mean you have to use the maximum available leverage.

Profit/Loss (P/L) Ratio

P/L Ratio = Holding P/L / Initial Margin

Trading Limit

In order to prevent malicious manipulation in the market, we introduce a trading limit mechanism. Under normal market conditions, the price of an order cannot exceed the index price ±10%.


Premium = Latest Market Price - Index Price

Premium Rate

Premium Rate = (Latest Market Price - Index Price) / Index Price

Funding Fee Adjustment Mechanism

Purpose: This mechanism makes the long and short forces in the market tend to balance. The funding fee adjustment frequency refers to each contract trading specification. Funding Fee Rate = Clamp(MA(((BID1 + ASK1)/2 - Index Price)/Index Price - Interest), a, b).

Pairs a b Interest
BTC/USDT [USDT]  -0.5% 0.5% 0%
ETH/USDT [USDT]  -0.5% 0.5% 0%

When the premium rate is positive, traders who hold long positions pay premium to those who hold short positions. If the premium rate is negative, traders who hold short positions pay premium to those who hold long positions. No payment occurs when the premium rate is 0. Special circumstances - When the system has a warehouse order, and it is not traded at the point when BIEX snapshots the premium price adjustment, the current fee of holding warehouse adjustment will be transferred to the warehouse funds. This mechanism is used to improve the exercise price of the warehouse order.

Price Improvement Mechanism for Warehouse Order

At the next premium price adjustment, the warehouse insurance funds will be used for the price improvements of the warehouse order, when the forced liquidation orders have been executed but not yet filled.

Insurance Fund

The warehouse fund is used to improve the forced liquidation orders, which have been executed but not filled. It is from funding fees and the over booking remaining BTC.

The Combination Of Forced Liquidation

Every time when funding fee price adjustment occurs, BIEX will combine all forced liquidation, which have not been traded. In addition, BIEX will use warehouse funds to improve the order prices of combined orders in order to make the trading process more convenient.
