In your trading software, as long as you enter the contract number of the relevant futures, the system will automatically prompt you how many hands you can open, which means you can buy or sell a few hands. However, some trading software will not automatically prompt you, and you need to press the open key before he will prompt you how many hands you can open.

If you want to know the number of lots of a fixed fund and a fixed futures product without using trading software, you also need to know the minimum margin ratio set by your futures exchange for this product. Because every futures transaction has its own margin ratio, you can multiply the real-time price of this futures by the percentage to get the amount of margin required for the first hand, and then divide the margin by your capital.

I'll make you a firm offer myself. That's all I can give you. I hope it helps you.
