Visit BingX Futures trading page and click on BTC, as indicated in the image below. Set your preferred order mode according to your preferences: by amount, by cost and by notional value.

1. Order by amount

2. Order by cost

Order by cost is based on the amount of cost you wish to invest, and the opening cost is not affected by leverage. The cost amount you enter includes the initial margin and trading fees, calculated in USDT.

For example, you place a BTC order at a price of 35,000 USDT with a 5x leverage and the "By cost" mode selected. Your opening amount will be approximately 0.0142 BTC. The required margin will be 99.4 USDT and the trading fee will 0.2485 USDT (due to the minimum order size limit in Futures Trading, the actual invested amount may be less than or equal to the entered cost).

Calculation formula:
Margin = order amount * order price / leverage = 0.0142 * 35,000 / 5 = 99.4 USDT
Trading fee = order amount * order price * trading fee = 0.0142 * 35,000 * 0.05% = 0.2485 USDT

3. Order by notional value

Order by notional value is based on the notional value you enter (affected by leverage) for investment, and the global unit will switch to USDT. Notional value is not equal to the actual invested amount.

For example, you place a BTC order at a price of 20,000 USDT with a 5x leverage and the "By notional value" mode selected. If you buy BTC with 100 USDT, the required margin would be 20 USDT.

Calculation formula:
Order amount = notional value / price = 100 / 20,000 = 0.005
Margin = order amount * price / leverage = 0.005 * 20,000 / 5 = 20 USDT

With a 5x leverage and an order of 100 USDT, the difference between order by cost and order by notional value is as follows:

• By cost: You manage approximately 500 USDT funds with a 100 USDT margin.
• By notional value: You manage approximately 100 USDT funds with a 20 USDT margin.
