The bull market does not talk about the top, which means that during the big rise, the market is violent and no one can guess where the top is.

Not eating the tail of the fish means that no matter where the top is, no matter how much it will rise, do not make money in the second half.

Not eating the tail of the fish means sacrificing profits to fight risks.

The big guys continue to optimize the tail of the fish theory, implement the pocket-taking, only keep a small part of the position, dynamic stop loss, and automatically clear the position once it falls to the position.

Keep most of the profits and use a small part of the position to try more possibilities.
