The seven stages of the banker's drawing are described as follows:

1. The accumulation stage: In this stage, the banker will collect chips in a low-key manner in the market, and the market performance is box-shaped oscillation. The overall volume begins to expand, and the upper and lower edges of the box are both volume peaks. It is rapid when falling, and it seems to be more dawdling when rising, frequently making investors feel that they are about to break through but fail to do so, so as to make retail investors tired and doubtful.

2. The first stage of pull-up: Once the banker has collected enough chips, it will start to pull up quickly, with the aim of quickly getting out of the cost area. Since retail investors have been deceived many times in the accumulation stage, they often dare not chase the rise at this time, which provides a good opportunity for the banker to pull up.

3. The first stage of washing: After the pull-up, the banker will carry out the first wash-up. The wash-up at this stage is often more in-depth, with a certain amount of shrinkage, which makes retail investors mistakenly believe that the stock price will fall below the previous low at any time, and then dare not easily intervene.

4. The second stage of pull-up: After the first wash-up, the banker will pull up again. The pull-up speed in this stage is slower and takes a longer time, making it difficult for retail investors to judge whether it is a rebound or a reversal. When the stock price breaks through the high point of the first stage, retail investors often realize it later, and the dealer has already prepared for another storm.

5. The second stage of washing: Compared with the washing in the first stage, the washing speed in the second stage is faster, and the plunge makes retail investors feel fearful. At the same time, the speed of pulling up is also accelerated, the purpose is to make retail investors in the market cut their losses and leave, while investors outside the market miss the opportunity to intervene because they have no time to react.

6. The third stage of pulling up: This is the fastest and largest wave of rise. The purpose of the dealer is to attract the attention of the entire market, through multiple extreme trends such as daily limits, so that retail investors have a strong desire to chase the rise, and then intervene at a high level. At this time, the dealer will pull and ship at the same time, and at the same time let retail investors have firm confidence in the rise of stock prices.

7. Shipping stage: In fact, in the process of the third stage of pulling up, shipping has begun. If the shipment is sufficient during the process of pulling up, the price of the currency may fall directly in the final stage; if the shipment is insufficient, the dealer will carry out shock operations at a high level to continue to attract retail investors to enter the market. At this stage, investors should focus on indicators such as turnover rate to judge the dealer's shipment situation.
