Don't be overly ambitious, just exit the market.

This afternoon, I was a bit greedy and didn't take advantage of the over 900 points of room—it's indeed a pity.
But it's okay, 700 points of room is also very attractive; securing the profits is the safest move.
Take profits when the opportunity arises, don't overthink, don't be greedy, and it's most comfortable to steadily lock in gains.
Make money you understand, avoid fighting battles you can't win, and don't be greedy—next time, you'll get it right again!
