If you're unfamiliar with perpetual contracts, please review our concept article on What are Perpetual Contracts (Derivatives)? first.
-
Visit https://www.jucoin.com/en and log in.
-
Hover your mouse pointer over the Derivatives option in the top navigation menu, then click on USDT-M Futures within the drop-down menu.
-
Within the trading interface, hover over the current trading pair symbol near the top left corner. By default, this should be BTC/USDT, which we will use for this example.
-
On the right side of the trading interface, you have the trading module. Click the Cross setting.
-
This window allows us to adjust the margin mode. We will continue with Isolated for this example. Tick the checkbox and click confirm.
-
Cross-margin extends the distance to your liquidation price by using other funds available beyond the initial margin you allocate to your position. However, if liquidation is triggered, you can lose all assets outside this position.
-
Isolated-margin ensures you only risk the exact amount of funds you allocate as margin for this single position, meaning other assets remain safe.
-
-
Click the Leverage setting next.
-
This window allows you to adjust the leverage through the +/- symbols, the field in the middle, or the slider below. We will use 10x leverage for this example. Click Confirm.
Remember: The more leverage you use, the higher your chance of liquidation.
-
Below the margin and leverage options, select Open (Close is used to close existing positions).
-
Next, you can select the type of order you wish to place. For this example, we will select Market to guarantee a position opens up immediately.
-
Market orders execute immediately at the best possible price(s) in the order book. Depending on the size of the position, you may experience some slippage.
-
Limit orders allow you to set the specific price at which you wish your order executes. There is no guarantee your order will execute as the price may not touch your desired limit price.
-
Trigger orders allow you to set advanced operations such as conditional orders or trailing stops.
-
-
The next section allows you to select the size of your position (how much you want to buy or trade). By default, you can enter the amount of BTC you wish to trade in the Size field or by using the slider. For this example, we will be opening a 0.5 BTC position.Optional: You can click the BTC menu for more options, such as selecting the size based on USDT Cost or USDT Nominal Value.
-
The final section allows you to review the USDT cost of your order, which fluctuates based on market price and leverage used. You can also see your estimated Liquidation price. This is the price at which you will lose the funds or margin allocated to this position. When ready, open a position. We will Open Long for this example.
-
Long positions are equivalent to betting the price will increase from your entry.
-
Short positions are equivalent to betting the price will decrease from your entry.
-
-
Review the details of your order once again and click confirm when ready.
-
Because we used a market order, a position will appear under the Position tab right away. You can see key information including your PNL/ROI.
-
To close your position, either to mitigate losses or secure profits, follow the same steps, but make sure you select the Close option and use the Close Long button.
