• Spread

The market depth will influence the spread. The spread ratio will be adjusted based on the change in market depth.
BTC/USDT Spread Range: 0.02% ~ 0.1%

• Trading Fee (Position Closing)

Calculation Method: Trading Fee = Trade Size * 0.045% 
For example: If an order is placed with 0.1 BTC as Principle with the 10x leverage, 
the trading fee is 0.1 x 10 x 0.045% = 0.00045 BTC.

• Funding Rate

Same as the USDT-Margined Standard Futures, when a user has held a position for more than an hour, the funding rate (charge/reward) will be calculated.

1) If the funding rate is positive, it means that the direction of the position needs to be charged for funding fee. 
However, if the funding rate is negative, it means that you can get a fee reward.

2) Funding occurs every 8 hours at 0:00, 8:00, and 16:00 ( GMT+8 ). 
Users can observe the current funding rate for a contract on the “ Position” page. 
Funding Rates will be settled when closing a position.

3) Calculation Method: 
Funding Fee = Total Contract Trade Size * Funding Rate. 
The funding rate is calculated by the platform at the time of charging.

6. Market Orders & Trigger Orders of the Coin-Margined Standard Futures

The mechanism of Market Orders and Trigger Orders with the Coin-Margined Standard Futures is the same as that of the USDT-Margined Standard Futures.

1) Market orders consume market depth and are filled immediately. There is a certain spread because they’re placed at the real-time market price.

2) "Trigger Order" is not " Limit Order". It is an automatic order tool, with which you can pre-set an order that will only be triggered under specific conditions.

3) Reasons Why Trigger Orders Fail

a. Trigger orders do not freeze the order principal, so after reaching the pre-set price, and your account balance is insufficient, the order will fail and the system will cancel the trigger order.

b. If the market price changes too much (such as the index closing at a low price or opening at a high price), and the difference between the market price and the pre-set price is greater than 1.5%, the trigger order will fail and the system will cancel the order.

9. Example of calculating PnL for the Coin-Margined Standard Futures

Transaction Direction: 1 refers to Long, -1 refers to Short.

Gross PnL= [Trade Size * Exchange Rate When Position Opens * (Closing Price-Opening Price) / Closing Price] / Exchange Rate When Position Closes
= Transaction Direction * Trade Size * Opening Price * (1 / Opening Price-1 / Closing Price)
Gross PnL Ratio = Transaction Direction * Trade Size * Opening Price * (1 / Opening Price-1 / Closing Price) / Margin
Net PnL = Transaction Direction * Trade Size * Opening Price * (1 / Opening Price-1 / Closing Price)-Trading Fee-Funding Fee

Please note: There is a characteristic for BTC/ETH Inverse Contract. When the price rises, the profit (loss) goes slow; when the price falls, the profit (loss) goes fast.

Examples are as follows:

Trade Size:10 BTC; Margin: 10 BTC; Leverage:1X
1) If the price rises by 100%, the income is 50% (Transaction Direction: Long; BTC Price 100 → 200).
2) If the price rises by 100%, the loss is 50% (Transaction Direction: Short; BTC Price 100 → 200).
3) If the price falls by 50%, the loss is 100% (Transaction Direction: Long; BTC Price 100 → 50).
4) If the price falls by 50%, the income is 100%(Transaction Direction: Short; BTC Price 100 → 50).

Calculate with the example of 2) :
Gross PnL Ratio
= Transaction Direction * Trade Size * Opening Price * (1 / Opening Price-1 / Closing Price) / Margin
= -1 * 10 * 100 * (1/100-1/200) / 10
= -50%

🔼 Calculation of Forced-Liquidation for the Coin-Margined Standard Futures in Isolated-Margin mode. The example is based on the BTC-Margined Contract.

When the Net PnL reaches -90%, the Forced-Liquidation will be triggered.

Calculation Method:
Liquidation Price = Transaction Direction * Trade Size * Opening Price / (0.9 * Margin + Transaction Direction * Trade Size - Trading Fee - Funding Fee)

Please note: Due to the difference in PnL, even with the same parameters, the Liquidation Price will be different between USDT-Margined orders and Coin-Margined orders.
For example: USDT-Margined, Long, 1x, Opening Price 100 USDT; Liquidation Price = 10 USDT.
BTC-Margined, Long, 1x, Opening Price 100 USDT; Liquidation Price = 52.63 USDT.
