In the world of cryptocurrency trading, perpetual and futures contracts have become essential tools for investors looking to hedge risk or speculate on price movements. This article breaks down the core concepts, fee structures, and mechanisms behind one popular platform’s offerings.
Understanding Crypto Derivatives
Cryptocurrency derivatives, such as futures and perpetual contracts, allow traders to speculate on the future price of digital assets without owning the underlying coins. These financial instruments can provide significant leverage, amplifying both potential gains and losses.
Core Contract Specifications
Each futures contract represents a fixed dollar value:
- Bitcoin (BTC) contracts: $100 per contract
- Other cryptocurrencies (e.g., LTC, ETH): $10 per contract
Traders can take long (buy) positions if they anticipate prices rising or short (sell) positions if they expect prices to fall. Leverage options commonly include 10x or 20x, meaning a trader can control a large position with a relatively small amount of capital.
How Leverage and Profits Work
The platform's unique contract design ensures leverage remains stable at the chosen multiple (e.g., 10x or 20x), calculated based on the fiat currency (USD) value. This stability makes it easier to manage risk and calculate potential profits or losses.
Example: If you buy 50 BTC contracts with 20x leverage and the price of Bitcoin increases by 5%, your gain in USD terms would be 5% * 20x = 100%. This stable leverage is a key feature for effective risk management.
Anti-Manipulation and Safety Mechanisms
To ensure a fair trading environment and protect users from market manipulation, several robust mechanisms are in place:
- Multi-Exchange Settlement Price: The final settlement price for contracts is derived from the average price across six major exchanges. This prevents bad actors from manipulating the price on a single platform.
- One-Hour Arithmetic Average: The settlement price is calculated based on the arithmetic mean of prices during the last hour of trading, reducing the impact of anomalous, last-second trades.
- Dynamic Price Limits: Order prices are restricted based on both the spot market price and the previous minute's contract price. This helps prevent malicious "stop hunting" or forced liquidations through sudden, fake price drops.
- Improved Liquidation System: In cases of extreme volatility, the system uses a composite price to determine liquidations, rather than a single erratic trade. This protects users from being unfairly liquidated due to a momentary price spike or crash.
Trading Fee Structure
Fees are based on a tiered system determined by a user's 30-day trading volume or their holdings of the platform's native exchange token, OKB. The system applies to both individual and sub-accounts, with sub-accounts inheriting the fee rate of the main account.
Fee Tiers for Standard Users
| Level | OKB Holding | 30d Volume (BTC) | Maker Fee | Taker Fee |
|---|---|---|---|---|
| Lv 1 | < 500 | < 1,000 | 0.100% | 0.150% |
| Lv 2 | ≥ 500 | < 1,000 | 0.090% | 0.135% |
| Lv 3 | ≥ 1,000 | < 1,000 | 0.080% | 0.120% |
| Lv 4 | ≥ 1,500 | < 1,000 | 0.070% | 0.105% |
| Lv 5 | ≥ 2,000 | < 1,000 | 0.060% | 0.090% |
Fee Tiers for High-Volume (VIP) Users
| Level | 30d Volume (BTC) | Maker Fee | Taker Fee |
|---|---|---|---|
| VIP 1 | ≥ 1,000 | 0.060% | 0.080% |
| VIP 2 | ≥ 5,000 | 0.040% | 0.075% |
| VIP 3 | ≥ 10,000 | 0.020% | 0.070% |
| VIP 4 | ≥ 20,000 | 0.000% | 0.060% |
| VIP 5 | ≥ 50,000 | -0.002% | 0.050% |
Note: The fee tier is determined by whichever qualification is met first—either the 30-day trading volume (across spot and contracts) or the OKB holding amount. Higher tiers offer progressively lower maker fees, and at the highest levels, makers can even receive a rebate, meaning they are paid to provide liquidity.
Understanding Maker vs. Taker Fees
- Maker: A maker adds liquidity to the order book by placing an order that isn't immediately matched (e.g., placing a buy order below the current market price). Makers typically pay lower fees.
- Taker: A taker removes liquidity by placing an order that immediately matches an existing order (e.g., buying at the current lowest sell price). Takers pay higher fees.
For futures and perpetual contracts, the fee calculation is similar. The trading volume for determining your tier is calculated by converting all trades into their BTC equivalent value every day at UTC 0:00.
Withdrawal Limits
Daily withdrawal limits are also tier-based and are calculated by converting the value of all withdrawn cryptocurrencies into BTC.
- Standard Users (Lv1): 300 BTC daily limit
- VIP Users: Limits increase with each level, up to 1000 BTC for the highest tiers.
It's important to note that these limits are also affected by your account verification level (KYC). Basic verification has a lower cap than advanced, fully verified accounts. 👉 Explore advanced trading platforms and their fee structures
Frequently Asked Questions
What is the main advantage of trading futures contracts?
The primary advantage is the ability to use leverage to amplify returns from small price movements. It also allows for hedging existing spot holdings against potential downside risk and enables speculation on both rising and falling markets.
How are trading fees actually charged?
In spot trading, the fee is deducted from the currency you are buying. For example, if you buy BTC with USDT, the fee is paid in BTC. In contract trading, fees are deducted from your account's collateral. Maker and taker fees apply based on your order type.
What happens if the market is extremely volatile?
The platform's improved liquidation system activates. Instead of using a single bad tick price, it uses a composite price to determine if a position should be liquidated. This prevents unfair liquidations during short-term price spikes or crashes, offering significant protection.
Can my withdrawal limit be increased?
The daily withdrawal limit is automatically set based on your fee tier and KYC level. If you require a limit beyond your current tier for legitimate reasons, you must contact customer support to discuss your options with an account manager.
Is the leverage really fixed?
Yes, a key feature is that the leverage multiplier remains stable relative to your USD-denominated profit and loss. Whether the price moves up or down, the leverage effect on your fiat-based equity remains constant at your chosen level (10x, 20x, etc.), simplifying position management.
How is the settlement price for quarterly contracts determined?
To prevent manipulation, the settlement price is not based on a single exchange. It is calculated as the arithmetic average of the underlying index price across six major exchanges over the final hour of trading, ensuring a fair and representative value.
