Why don't you recommend playing contracts? You should first figure out the accounts.

For example: you put in 1000u as margin. If the position shows a 100% profit rate, you will find that your margin is only 860u, which means that you have not realized the good thing at this time is +860u, not +1000u

But your position shows a loss of 100%, and it also explodes. It is not a stop loss, but a liquidation. You will find that you actually only lost 840u, and there is 160u for the liquidation fee.

It means that if you win, it will reduce your profit for no reason.

If you lose, it will make things worse for you.
