Contracts really test human nature, I suggest everyone not to play; basically, as long as you don't exit, 99% of those who play contracts end up liquidated to zero.

I have some experienced contract traders around me, and after years of playing, it's good enough if they don't lose; most of them are just giving transaction fees to the exchanges, and many are losing money.

When playing contracts, the big sharks cut you, the exchanges cut you, retail investors gamble against you; everyone is your opponent, so tell me how to win?
