In this bull market, it is mostly impossible to accurately time the peak. Unlike previous years, where spot trading was dominant, this round is contract-driven. Furthermore, the decline may occur as a continuous downward trend for 1-3 months. This is the power of hedging; if you don't believe it, try it out. Anyway, the captain has no confidence in being able to time the peak, so the higher it goes, the more I will gradually exit.
