The double shadow line in the stock indicates that there is no effective breakthrough at the same price twice, so it is necessary to consider falling back before breaking through. The origin of the double shadow line dishwashing statement: Generally speaking, the market is concerned about the long shadow line or the double shadow line. The upper shadow line or the double upper shadow line is the K-line indicating that the stock price trend of the market or individual stocks is about to turn down. The most classic thing is that when the market or stock price experienced a big rise, the stock index (stock price) opened higher and then rose, but then fell sharply, closing out a negative line with a long shadow line or double shadow line. This situation indicates that the current market will turn around at any time and enter the downward channel. This kind of psychological suggestion is often used to try and wash dishes in practice.

Common stock form:

1, head and shoulder type:

After the K-line gathers for a period of time, there will be three vertices or bottoms in a certain price range, but the second vertex or bottom is higher or lower than the other two vertices or bottoms. This type is called head-shoulder type. One with two shoulders is the top of the head and shoulders; The one with one bottom and two shoulders is the head-shoulder bottom type. However, sometimes there may be more than three vertices or bottoms. If there is one or two heads (or bottoms) and two left and right shoulders, it is called a composite head and shoulder top (or a composite head and shoulder bottom).

2. Inverted shoulder type:

It's also called the head and shoulder bottom. (I used to call it the shoulder bottom just because it is smooth, but it's actually easy to be confused with the shoulder bottoms of the two shoulders on the left and the two shoulders on the right! Its shape is as shown in the figure, with three obvious bottoms: left shoulder, right shoulder and head. The decisive breakthrough of neckline in the market price is a necessary condition for the completion of the whole form. However, as the reverse shape of the bottom, the head and shoulders often supplement (pull back) the neckline to confirm the effectiveness of the shape. Once the neckline is effectively broken in the counterattack, the form will be suspended! The market outlook will continue along the downward line!

3, double top form:

It is formed after the stock price rises to a certain stage, and there are two peaks in form, namely the left peak and the right peak. Theoretically, the two high points of the double top should be basically the same, but in the actual K-line trend, the left peak is generally slightly lower than the right peak, with a difference of about 3%. In addition, the first peak (left front) forms a low point of falling back, and a horizontal line is drawn at this position to form the so-called neckline. When the stock price rises again and falls below the support of this horizontal line (neckline), the double-top form is officially announced. In the process of forming double peaks, the volume of left peak is larger, followed by right peak. The volume of transactions is decreasing, which shows that the pursuit of funds in the stock price is getting weaker and weaker in the second rebound, and the stock price has the meaning of rising to the end. After the formation of the double top, the stock price tends to pull back in the process of falling, but the pull back is not strong, and the neckline position constitutes strong resistance.
