Our trading fees are different for regular and VIP users. Regular users are categorized into tiers by their total OKB holdings whereas VIP users are categorized by 30-day trading volumes and daily asset balances. Tiers are updated daily.

If users meet the conditions of different fee tiers in terms of spot trading volume, total trading volume of futures and perpetual contracts (USDT-margined and crypto-margined), options trading volume and total assets, they will enjoy the fee discount of the highest fee tier. For example, if a user's 30-day spot trading volume is 20,000,000 USD (VIP 2); his 30-day total trading volume of futures and perpetual contracts (USDT-margined and crypto-margined) is 200,000,000 USD (VIP 3); his 30-day options trading volume is 5,000,000 USD (VIP 1); and his total assets as of today is 5,000,000 USD (VIP 4), he will enjoy fee discounts in all markets as a VIP 4 user.

Total OKB holding

Total OKB holding is the total amount of OKB that you have in both primary and sub-accounts. Including spot and margin accounts (OKB in Savings are not included).

Primary and sub-accounts

The tier of your primary account is determined by 30-day trading volume and daily asset balance of all primary and sub-accounts. Fee level of your primary account will be applied to your sub-accounts at 10:00 am UTC after sub-account created.

30-day trading volume (USD)

Transactions are recorded in BTC equivalents according to price when trading. Every 24 hours, we convert your total trading volume to USD at 16:00 UTC according to the average price (= [closing price + opening price]/2). For example, you have traded OMG, XUC, BTC, LTC and BCH in the last 30 days. We recorded each transaction in BTC equivalents at the moment of each trade happens. At each 4:00 pm UTC, we calculate your total trading volume in the last 30 days and convert it to USD according to the daily average price.

For spot markets, we charge trading fees in base currencies. For example, if you trade BTC/USDT, we charge trading fees in BTC. But if you trade USDT/BTC, we charge fees in USDT.

You can also get fee rebates from us. They’re paid in the same currencies as trading fees. For example, if you trade BTC/USDT and place a BTC sell order, you can get a trading fee rebate in BTC. If another user places a BTC buy order and you fill it, you can get a rebate in USDT because another user pays trading fees in USDT for this order.

Total asset balance

We take a snapshot of users' all crypto assets at 4:00 pm UTC daily and convert the value to USDT, then to BTC based on the daily average price of BTC/USDT (BTC/USDT middle price = [opening price + closing price]/2).

Snapshot assets include classic accounts (spot, margin, futures, perpetual swap and options), trading account (unified account), funding account and finance account. Assets borrowed for leverage or loan are excluded.

30-day trading volume (USD)

We calculate the total 30-day volume of all your futures trades in BTC according to BTC/USD price. Every 24 hours, we convert the total volume to USD according to the average price, which is the halved sum of open and close prices. We settle it at 16:00 UTC daily.

Let’s say, you traded BTC, ETH, and ETC crypto-margined futures within the last 30 days. We’ll convert your trading volume to BTC equivalent according to BTC/USD rate and then convert to USD according to the average price. Then we’ll settle the volume at 16:00 UTC.

Makers and takers

Maker order is the limit order which enters into the order book before it can be traded in market. For example, if the current BTC lowest ask price is 1,000 USDT and you create a maker order with a bid price 9,99 USDT, this order cannot be filled immediately. Then it will enter into the order book until someone fills it. After filled, you're required to pay the maker fee and taker will pay the taker fee. Vice versa, you need to pay the taker fee when your limit ask order traded successfully.

Then it will enter into the order book until someone fills it. After filled, you're required to pay the maker fee and another user will pay the taker fee. The final fee can’t exceed 12.5% of the option premium.

Calculation of maker and taker fees:

Maker fee = Min. (maker fee rate * contract multiplier * number of contracts, options price * contract multiplier * number of contracts * 12.5%)

Taker fee = Min. (taker fee rate * contract multiplier * number of contracts, options price * contract multiplier * number of contracts * 12.5%)

Settlement fee

The settlement fee for futures is 0.03% for all users regardless of tiers.

Forced liquidation fee

The forced liquidation fee for futures is calculated according to the taker fee of current user tier.

Option exercise fee

The exercise fee for options is 0.03% for all users regardless of tiers. This fee of a single contract will not exceed 12.5% of the exercise profit. 1-day and 2-day options do not have the exercise fee. The options that haven't been exercised are fee free too.

Close a position and forced liquidation fees

The option fee of closing a position fee is calculated according to the maker/taker fee of your current tier. The forced liquidation fee is based on the Tier 1 taker fee. You can learn more about option fees in the Options Guide.

Only short position users will be charged a penalty fee when closing a position. It's 0.03% for these users regardless of tiers. Penalty fee will be added to the insurance fund at the time of settlement.

Both close a position and forced liquidation fees will not exceed 12.5% of the option fee.

24h withdrawal limit (BTC)

If you want to withdraw 20 BTC qeuivalent in XRP, which exceeds 10 BTC limit, you can withdraw until the next day.
