The supply continues to shrink. After the low-bottom test, it shows that the last support of LPS is currently being built, and the profit-loss ratio of long-term entry is excellent. After the previous volume broke through and returned to the range, the volume decreased twice, and then was swallowed by the positive line with volume, indicating that the demand was rising. Although it is currently under the suppression of multiple moving averages, the method on the left can still judge that the accumulation behavior below is being established. Once the accumulation is completed, the volume breaks above the moving average and is very optimistic.
