The previous article mentioned that $BTC turned around, which means: originally we were in an upward trend, and the normal trend-based order was to go long on every pullback, but the trend turned around, which means that the upward trend was directly destroyed.
That is, we directly entered the initial stage of the downward trend, and we had to adopt the strategy of shorting on highs in a small cycle.
Look at the example below. The original trend was going well. Even if the trend did not continue, it would be normal to go sideways. However, a large negative line has destroyed the original trend.
