$BTC I have set a strict rule for myself, which is that after breaking the major downward trend line, I will resolutely not go short. If I do both long and short, in case I get trapped in a short position, I might accidentally short the main upward wave, and then I will basically miss out on the profits of the main upward wave. Because very few people dare to chase the rally after stopping out of a short position. The main upward wave will not have large pullbacks to give you an entry.
