Trading fees examples

Assume multiplier is 0.01 for BTCUSD options, contract size is 1 BTC, option premium is 0.05 BTC.

Trader A (maker fee: 0.02%, taker fee: 0.03%) bought 100 contracts of call options (notional is 1 BTC):

If trader A is the taker when order is filled, the trading fee = Min (0.03% × 0.01 × 1 × 100, 7% × 0.05 × 0.01 × 1 × 100) = 0.0003 BTC

If trader A is the maker when order is filled, the trading fee = Min (0.02% × 0.01 × 1 × 100, 7% × 0.05 × 0.01 × 1 × 100) = 0.0002 BTC

Options combo examples

Combo trades	Fees
Buy 1 BTC call, buy 1 BTC put	Fees are charged on both legs. Same applies if both are sell legs.
Buy 3 BTC call, sell 2 BTC put	Fees are only charged on the buy 3 BTC call leg
Buy 3 BTC call, sell 2 ETH put	Fees charged on both options legs and total gross notional.
Buy 3 BTC call, sell 2 BTC put, buy 2 ETH call, sell 2 ETH put	The calculation method applies to the BTC structure and ETH structure separately. In this example, trading fee is charged on the buy 3 BTC leg and the buy 2 ETH leg.
Buy 3 BTC call, sell 2 BTC put, buy BTC Perp hedge	The calculation method applies only to options. In this example, trading fee is charged on the buy 3 BTC leg and the buy BTC Perp hedge.

Main and sub-accounts fee tier

The fee tier of your main account is determined by the 30-day trading volume and snapshotted daily asset balance of all main and sub-accounts. Fee tier of your main account also applies to your sub-accounts at 4:00 pm UTC after the sub-accounts are created.

30-day trading volume (USD)

Crypto pairs

Calculate your trading volume in BTC based on its current USD value. Daily, at 4:00 PM UTC, we convert your total trading volume to USD using the daily middle price of BTC/USD [Middle price of BTC/USD = (Opening price + Closing price) / 2]. We then determine your total spot trading volume over the past 30 days. For example, if you have traded BTC, ETH, and MATIC in the last 30 days, we convert each transaction to its BTC equivalent at the time of the trade (this includes trades in USDT, ETH, and other pairs). This amount is then converted to USD based on the daily middle price, and finally converted to USD based on the exchange rate. Daily, at 4:00 PM UTC, we update this calculation to reflect your trading volume over the past 30 days.

USD pairs

Transactions are recorded in USD equivalents according to its price at the moment of trading. For example, you have traded USDT/USD pair in the last 30 days. We recorded each trade in USD equivalents at the moment when each trade happened. Each day at 4:00 PM UTC, we calculate your total trading volume in the last 30 days.

30-day trading volume (USD)

Calculate your trading volume in BTC based on its current USD value. Daily, at 4:00 PM UTC, we convert your total trading volume to USD using the daily middle price of BTC/USD [Middle price of BTC/USD = (Opening price + Closing price) / 2], and finally converted to USD based on the exchange rate. We then determine your total futures trading volume over the past 30 days.
For example, if you have traded BTC, ETH, and ETC crypto-margined futures in the last 30 days, we convert each transaction to its BTC equivalent at the time of the trade. This amount is then converted to USD based on the daily middle price, and finally converted to USD based on the exchange rate. Daily, at 4:00 PM UTC, we update this calculation to reflect your trading volume over the past 30 days.

We then determine your total options trading volume over the past 30 days.
For example, if you have traded BTC and ETH options in the last 30 days, we convert volume of BTC and ETH to its BTC equivalent at the time of the trade. This amount is then converted to USD based on the daily middle price, and finally converted to USD based on the exchange rate.

30-day trading volume (USD)

Calculate your trading volume in BTC based on its current USD value. Daily, at 4:00 PM UTC, we convert your total trading volume to USD using the daily middle price of BTC/USD [Middle price of BTC/USD = (Opening price + Closing price) / 2], and finally converted to USD based on the exchange rate. We then determine your total spread trading volume over the past 30 days.
For example, if you have traded BTC and ETH options in the last 30 days, we convert volume of BTC and ETH to its BTC equivalent at the time of the trade. This amount is then converted to USD based on the daily middle price, and finally converted to USD based on the exchange rate. Daily, at 4:00 PM UTC, we update this calculation to reflect your trading volume over the past 30 days.
A spread trade’s volume is calculated as the sum of all the individual legs. Volume of all spread combinations are treated the same. For example, 1 USD’s worth of spot-perpetual spread trade is treated the same as 1 USD’s worth of futures-futures spread trade.

Total asset balance

We take a snapshot of all of your crypto assets at 4:00 PM UTC daily and convert the value to BTC, then to USD based on the daily middle price of BTC/USD [Middle price of BTC/USD = (Opening price + Closing price) / 2]. The higher value between the past 30-day average asset amount and the daily snapshot is used as the user’s asset amount. Finally, the total amount is converted into USD using the day’s exchange rate.
For example, if the 30-day average asset amount is 1,000 USD and the snapshot at 4:00 PM UTC shows 500 USD, the user’s asset amount will be 1,000 USD.
Total assets include both your crypto and any fiat assets.

Makers and takers

A maker order is a limit order that enters the order book and isn’t filled immediately.

For example, if the lowest BTC ask price is 1,000 USDT and you place a buy order at 999 USDT, it won’t match right away and will remain in the order book until someone fills it.
Once filled, you’ll pay the maker fee, while the counterparty (the taker) pays the taker fee.

Trading fee rules

Calculating trading fees:
Fee for spot trading = Fee rate × Amount of crypto bought when order was filled.
Take USDT/USD as an example, assuming the current price of USDT is 10 USD. If trader A (0.04% for maker fee and 0.1% for taker fee) buys 1 USDT at the market price. As a taker in this trade, A’s trading fee = 0.1% × 1 = 0.001 USDT. After the trading fee deduction, A receives 0.999 USDT from this trade.
Conversely, if A sells 1 USDT at a limit price and buys 10 USD, A is considered the maker in this trade. In this case, A’s trading fee = 0.04% × 10 = 0.004 USD. After the trading fee deduction, A receives 9.996 USD from this trade.

Trading fee rules for spreads

Calculation of trading fee for each leg: same calculation method applies for each corresponding instrument, with a 50% discount applied for all users.

For example, Trader A is trading a BTC spot vs USDT-margined perpetual spread.
The spread trading fee is derived by taking the sum of:
1. Spot trading fee rate at 50%, so Trading fee = 50% × Spot fee rate × Amount of bought or sold crypto
2. USDT-margined perpetual fee rate at 50%, so Trading fee = 50% × Perpetual fee rate × Number of contracts × Multiplier × Contract size × Fill price.

Trading fee rules

USDT-M perpetual and expiry, USDC-M perpetual and expiry
Calculation formula of trading fee: Trading fee = Fee rate × (Number of contracts × Multiplier × Face value per contract × Fill price).
Charge rule: Trading fee of USDT-M perpetual and expiry is settled in USDT, and trading fee of USDC-M perpetual and USDC-M expiry is settled in USDC, and is charged when the order is filled;
Take BTCUSDT perpetual futures (Face value is 0.01 BTC, Multiplier is 1) as an example, assuming the current price of BTC is 20,000 USDT;
Trader A (Maker fee: 0.02%; Taker fee: 0.05%) bought/sold 100 contracts (1 BTC) at market price with 10x leverage, and used 2,000 USDT (0.1 BTC) as margin. Trader A became a taker of this trade, so the Trading fee = 0.05% × (100 × 1 × 0.01 × 20,000) = 10 USDT;
Trader A bought/sold 100 contracts (1 BTC) at limit price with 10x leverage, and used 2,000 USDT (0.1 BTC) as margin. Trader A became a maker of this trade, so the Trading fee = 0.02% × (100 × 1 × 0.01 × 20,000) = 4 USDT.

Crypto-M perpetual and expiry
Calculation formula of trading fee: Trading fee = Fee rate × (Number of contracts × Multiplier × Face value per contract / Fill price).
Charge rule: Trading fee for Crypto-M perpetual and expiry is settled in the traded crypto and is charged when the order is filled;
Take BTCUSD perpetual futures (face value is 100 USD, Multiplier is 1) as an example, assuming the market price of BTC is 20,000 USD.
Trader A (Maker fee: 0.02%; Taker fee: 0.05%) buys and sells 100 contracts (10,000 USD) at market price with 10x leverage, and uses 0.05 BTC (1,000 USD) as margin. If Trader A is the taker of this trade, the trading fee = 0.05% × (100 × 1 × 100 / 20,000) = 0.00025 BTC;
Trader A buys or sells 100 contracts (10,000 USD) at limit price with 10x leverage, and uses 0.05 BTC (1,000 USD) as a margin. If Trader A is the maker of this trade, the trading fee = 0.02% × (100 × 1 × 100 / 20,000) = 0.0001 BTC.

Expiry settlement fee: 0.01% for all users regardless of tier level.
Forced liquidation fee: Calculated according to the taker fee of user’s current tier level.

24h crypto withdrawal limit (USD)

User’s 24-hour withdrawal limit is calculated daily at 4:00 PM UTC based on the fee level. All crypto held by the user will be converted to USD, and the total converted amount must not exceed the withdrawal limit of the corresponding level.

For example, your 24-hour withdrawal limit is 300 USD. After withdrawing 250 USDT, 25 USD equivalent in OMG, and 15 USD equivalent in XRP, you used 290 USD of the withdrawal limit. This means you have 10 USD remaining within the 24-hour period. If you want to withdraw 20 USD equivalent in XRP, which exceeds the 10 USD remaining balance, you can’t withdraw until the next day. Alternatively, you can contact our customer support to increase your limit tentatively.
