2. Concept plate classification: There is no uniform classification standard for this classification, and there are several plate categories: policy classification, regional classification and hotspot economy classification.

the two-step and five-step stock selection method is:

the first step: adjust the ratio

after the opening, first adjust the 6-ranking list and adjust the ratio, because as long as there is quantity, this stock will have the opportunity to soar at any time, and if there is no quantity, the stock price will definitely be greatly affected. The so-called quantity comes first, the price comes last, and the quantity and price rise together.

step 2: look at the time-sharing chart

when looking at the time-sharing chart, the trend of the time-sharing chart conforms to the method of shooting the moon with a bow, supported by the moving average, and the real-time change line grows step by step without falling below the average price line.

Step 3: Look at the K-line

to bring up the Brin track line, type BOLL on the keyboard, and enter will come out. The trend of the K line is supported by the middle rail of the bollinger Band, that is, the white line, and the K line cannot fall below. Another condition is not to chase after the high price. If there is a trend of daily limit at the opening, it will explode in time and you can't buy it at all, so don't chase after it, because this stock is not cost-effective.

Step 4: Look at the increase

There are already stocks with a large amount of early trading, and stocks with an increase of more than six points should not be chased. Choose to buy stocks with an increase of less than five points, so as to ensure that there is some room for growth after buying.

Step 5: Look at the turnover rate

Choose those with turnover rate above 5%, preferably above 7%. Those with low turnover rate will not be considered for the time being. Of course, it doesn't mean that there are no stocks with daily limit, because the probability of daily limit with low turnover rate is small.
