Yes. 1. Users decide the long and short direction based on their judgment of the BTC price trend, and select the contract type based on the length of time. Currently OKEX (you can click to register an account if you don’t have an account) provides three contract types: current week, next week, and quarter. The current week's contract refers to the contract that is delivered on the Friday closest to the trading day; the next week's contract refers to the contract that is delivered on the second Friday closest to the trading day. The quarterly contract means that the delivery date is the last Friday of the month closest to the current month among March, June, September and December, and does not coincide with the delivery date of the current week/sub-week/monthly contract.

2. The user chooses the appropriate price and quantity to complete the transaction. When a user purchases a contract, the required margin is the number of BTC equal to the transaction time and contract value divided by the leverage multiple. Only when the account equity is greater than or equal to the amount of margin after the transaction is successful, the user can perform entrustment operations.

3. Margin When establishing a contract trading account, users need to select a margin mode. Different margin modes have different trading margin calculation methods and risk control systems. When there are no positions and no pending orders, that is, when the margin of all contracts is 0, the user can change the margin mode. When using the cross margin mode, the risks and benefits of all positions in the account will be calculated together. Under the cross margin mode, the requirement for opening a position is that the margin rate after opening the position cannot be less than 100%. When using the isolated margin mode, the margin and income of each contract's two-way position will be calculated independently. Only when the available margin for opening a position is greater than or equal to the amount of margin required for opening a position, the user can place a commission. When using isolated margin, the available margin for opening a position on each contract may be inconsistent.

4. After the transaction is completed, the user holds the position corresponding to the long and short direction. Under cross margin, the user's account equity will increase or decrease according to the latest transaction price; under cross margin mode, when the user's account equity is less than 10% of the margin at 10 times leverage, the BTC contract account equity is less than 10% of the margin at 20 times leverage. When the equity is less than 20% of the margin, the system will force liquidate the position. Under isolated margin, the unrealized profit and loss of a user's position in a certain direction of a certain contract will increase or decrease based on the latest transaction price, but the margin will not change. When the margin ratio of a user's position in a certain direction of a contract is less than or equal to 10% (10 times leverage) or 20% (20 times leverage), the system will force liquidate the position.

5. After the position is completed, the user holds the position corresponding to the long and short direction.

6. Adjust positions Users can also adjust positions at any time according to market conditions, lock in profits or stop losses by closing positions, or continue to open positions to increase profits.

7. On the delivery day, open positions will be closed based on the delivery index at a price of one dollar per point. All profits generated from closing positions will be summarized into the "Realized Profit and Loss" item of the user's contract account. After the delivery is completed, the system will deduct the loss of the user who has exceeded the position in proportion to all accounts with net profits from the contract.

8. After the settlement is completed, all realized profits and losses will be summarized into the account balance.

9. End the contract and the exchange will issue a new contract. How much is the contract handling fee on ok Exchange?
