(1) Calculate the theoretical height of rebound.

The method is to subtract the lowest point from the highest point, divide by 2, and add the lowest point, which is the final theoretical rebound height.

Its calculation formula can be expressed as: x (theoretical increase) = D (lowest point or lowest price) +[H (highest point or highest price) -d (lowest point or lowest price) ]> 2.

Use example: the calculation of rebound height 1776 points in 2004;

X (rebound height) = 1307 points+[2245 points (highest point)-1307 points (lowest point)] ÷2= 1776 points.

Through calculation, the theoretical rebound height in 2004 should be 1 176 points. The highest daily closing point on April 6, 2004 is actually 1777, which is only one point away from the calculation result, and its accuracy is obvious.

At that time, Yin reminded the media a few weeks in advance that "the pressure at 1776 is worthy of attention". As a result, the actual trend was only a little worse than its forecast, and the market outlook plummeted 14 months until 998 points. At that time, because many investors were superstitious about fundamentals, they didn't listen to Yin's advice, but didn't throw away their stocks. As a result,/kloc-was eliminated by the market in 0/4 months.

⑵ Calculation of falling low point.

Yin said: "This is a good way to buy stocks at a low level. Accordingly, buying stocks can generally buy a safe lowest price area. "

Its calculation method is to subtract the obvious high point of the previous period twice from the obvious low point of the previous period, and the negative number is the lowest point or the lowest price of its theoretical decline.

Expressed by the formula: x (buying price) = H (previous high point)-low-low.

Use case 1: Buy China Unicom (600050) at a low price.

Time: 165438+2002 10 month.

After China Unicom went public in 2002, there was an obvious high of 3.09 yuan on June 5, 2002, and then it fell to June 27, 2002, with the lowest price of 2.85 yuan. At this time, the rebound left a low point. Later, the stock fell below the low of 2.85 again at 65438 on February 26th. At this time, a buying formula is established: subtract the remainder of the previous low of 2.85 from the highest closing price of 3.09 yuan, and then subtract 2.85 to get a negative 2.6 1 yuan. Then, you can increase 0 yuan by 3 cents at the exchange rate of 2.665438+ Man Cang. After the actual Unicom fell to 2.62 yuan, it pulled out the positive line on June 7, 2003, and rose to 5.36 yuan near the daily limit on the 8 th, with a net profit of 204.5%.

Xu Wenming's box theory;

1, target increase: 28.2% (one box)

Bottom price x 28.2%;

Multiplied by 3 times 28.2% and then multiplied by 6.4%= top;

Head = 6.4% behind at least two box bottoms;

(In Gann's box theory, 6.4% is the basic box, and the four boxes add up to 28.2%. )

Flexible operation methods of box theory: short, medium and long lines, each with short, medium and long lines, but the application methods and principles are interoperable. The operation mode in actual combat is: after setting the pressure and support of the box, you can operate back and forth in the box for a short time, earning the price difference constantly, and then pay attention to the changes of the box at any time and compare the positions of the upper and lower boxes, that is to say, the support and pressure will be exchanged, the market will break through, the original pressure will become support, and the market will fall below. The original bottom support of the box will become the pressure of the current stock price. When the box changes,

2, 1/2 theory:

When a stock falls below the previous bottom, it must attract attention. Once the previous head subtracts the previous bottom = X, and then this x subtracts the previous bottom, then the bottom that can be reached this time; For example, the head in the early stage is A; The bottom of the early stage is b;
