The difficulty of futures discipline mainly lies in the novice's ignorance of duration.

Trading discipline is the law of the market. If you don't obey the discipline, it's illegal. People's behavior needs to be restrained by law, otherwise this society will be chaotic, and trading behavior also needs to be restrained by trading discipline, otherwise trading will take you to the abyss. Obeying discipline is as difficult as obeying the law. Because we always think that discipline is a constraint that always prevents us from trading and acting freely, we forget that discipline always protects our safety.
