In short-term trading, whether to go long or short really depends on the current market rhythm.

Sometimes when the market is surging, going long can capture significant gains; but during consolidation and oscillation, opening and closing positions frequently can easily lead to being cut. The same applies to short positions—there are opportunities when the market is weak, but if you follow the trend during a rebound to short, you need to be careful of getting trapped.

The key is to understand the short-term rhythm—where are the support and resistance levels, what is the trading volume, and what are the big players doing. Both technical and sentiment analysis should be considered; otherwise, even the best direction can be wasted.
