1, due to the active intervention of the main force, the originally dull stocks became active under the obvious amplification of trading volume, and there was a trend of rising volume and price. Then, in order to clear the way for the sharp rise in the future, the main force had to forcibly wash the short-term profit-making disk, which often showed a shock of one yin and one yang on the K-line chart. At the same time, because the main purpose is to get ordinary investors out, the K-line shape of stock prices often becomes an obvious "head shape".

2. In the main washing stage, the K-line combination is often overcast, and there are many overcast times. Every closing is accompanied by a huge volume, as if the main force is shipping on a large scale. In fact, careful observation shows that when there is a huge cloud above, the stock price rarely falls below the 10 moving average, and the short-term moving average strongly supports the stock price, and the main signs of low replenishment are clear at a glance.

3. When the main force washes the dishes, as the main indicator to judge the change of trading volume, there will also be some obvious characteristics, mainly as follows: when there is a huge amount of money, the moving averages of the stock price on the 5 th and 10 keep running upward, indicating that the main force has been adding positions, stock trading is active and the market outlook is promising. In addition, the quantitative index of trading volume, OBV, has always been upward during the period of large fluctuations in stock prices. Even if it falls back instantly, it will quickly rise and hit a new high in the near future. This shows that from the perspective of quantity and energy alone, the stock price has the conditions to rise.
