1, address book, historical lowest price function, historical highest price function.

{Historical Lowest Price} Historical Lowest Price: =LLV(L, 0); {Historical Highest Price} Historical Highest Price: =HHV(H, 0).

2. Find the formula of the main picture of Tongda letter: The master helped me to connect the highest stage price with the lowest stage price.

M3 5 100 20 M4 5 100 20 wire drawing (high & gt=HHV (high, M3), high and low =HHV (high, M4), low, 0); Adjust the parameters yourself, as long as it meets the individual stocks.

3. The formula for finding a communication letter = closing price-lowest price = highest price-closing price.

Multi-gravity: = c-l; Air force: = h-c; Draw number (dynainfo (7) = c and dynainfo (5) = h and dynainfo (6) = l, H+(H-L)*0. 1, Duoli), COLORGREEN draw number (dynainfo (7) = c and dynainfo (5) = h.

4. What should I do if stocks with the same price are at the bottom for two consecutive days?

Flat head and flat bottom are composed of two K lines (flat head) with almost the same level highest point or two K lines (flat bottom) with almost the same lowest point. There is another name, called tweezers top (flat top) and tweezers bottom (flat bottom), because the endpoints of these K lines are as flush as tweezers legs. In the rising market, when the "highest points" of several K-lines are equal, a flat head shape is formed. In the falling market, when the "lowest points" of several K-lines are basically the same, a flat bottom shape is formed.

5, morphological principle:

Flat head: In the process of rising exchange rate, the selling pressure of a high position is very large, and it may peak and fall back when the exchange rate fails twice in a row. Therefore, in operation, we should pay enough attention to such morphological characteristics.

Flat bottom: in the process of price decline, the short positions that push down the price gradually dry up, and the buying below the market continues to appear, and the price is about to rise because of the resistance of the seller at the same price. After two days (or several days) of short positions, the camp broke up. Then the bulls who push up the price take the initiative to attack, thus forming the bottom of the price operation, and the price may rise in the afternoon.

6. Trading strategy: There is a flat-headed form, so we should be prepared to reverse the original trend. When forming a flat head, you should carefully consider holding more than one order. You can consider all the positions to wait and see, or you can temporarily close some positions to ensure a certain profit.
