The end of the downtrend phase is usually accompanied by the emergence of a bottom divergence in the lower histogram.

Subsequently, there will be a period of range-bound oscillation, and trading volume will begin to increase within this range to accumulate shares.

Comparison method: Use the FRVP tool to measure whether the volume during the range oscillation can cover the volume from the previous downtrend.

When the price eventually breaks through the range, the histogram will also turn green. (This is not guaranteed)

Entry can be chosen after the breakout of this range, or after the histogram shows a bottom divergence, starting DCA to enter and continuously lower the average cost.
