From the perspective of long-term trading results, different rules will definitely have differences in capital returns. The higher the return, the more it aligns with price trends; this is the conceptual advantage. Trading is about trading your concepts, and the specific entry points are also a product of those concepts.
Therefore, one should not rigidly determine which point to go long and which point to go short. Both long and short can be correct, as prices move continuously, and this 'continuity' will produce many changes; only rules can handle price fluctuations.
