Short at the highest price is difficult, but shorting is not.

Shorting is about quick entry and exit; you can enter when there are weak trends and signals. Of course, you need to find a point to exit before it turns strong. This is how shorting is played, and often, shorting makes quick money.
Short at the highest price means trying to reach the peak, and making a big profit from shorting is very difficult, especially in a bull market. There is only one peak, and no matter how many times there is a pullback, a new high is always waiting for you. I see many friends losing money this round, and most of the losses are due to shorting at the top. Losing money from shorting at the big peak happens the fastest, and every time they short, they end up losing money.
Today I also shorted and lost 20wu. I originally could have returned to my cost but didn't exit. Then it pulled up a bit and I lost again, learning the same lesson.
