The premise of "going with the flow" is to clarify the price structure.
The simplest way to judge the price structure is to observe the rhythm of high and low points over a period of time.
Rising high and low points: bullish trend, mainly going long.
Falling high and low points: bearish trend, mainly going short.
Parallel high and low points: consolidation structure, selling high and buying low.
Judging the structure is essentially equivalent to judging the direction of the market's center of gravity migration.
