For example if we doing futures, the date set expired is 1 month, is it can't closed until expired?
I have not tried future contract before, I have have only preferred to go for perpetual contract that do not have the expiration date which is the difference.
But in accordance to what I have read about future contract, you can close the position opened at anytime before the expiration date, if not closed by you, it would close by itself after the expiration date.
If we get liquidated, is it true all our money gone, nothing left?
Yes, all the money would be gone (lost). That is the meaning of asset (or trading fund) liquidation.
Ok. Thanks for the information.
That is seem very risky.
we only get unrealized loss if don't sell the coin and the coin still there.
