The most common means of trial is to quickly find the starting point of profit once it is successful!
The characteristics of the examiner are summarized as "fast, urgent, short and small". Fast, that is, the test disk comes quickly without any warning;
Urgent, that is, ups and downs, come urgently, go quickly, people can't catch up; Short, that is, the market lasts for a short time, and some of them are only completed in a few minutes; Small means small fluctuation range and poor operability.
1, daily limit test
The main force mainly observes the comparison between the sales volume in the market and the amount of funds following the trend through the daily limit, and analyzes and judges the stability of the chips.
After the daily limit of the day, the next day will often start a heavy volume shock. On the third day after the daily limit, the stock price began to fall, or it was sideways.
On the one hand, the daily limit test can test the intraday selling pressure, on the other hand, it can also test the enthusiasm of followers, on the other hand, it can also appear in the leaderboard to attract attention and lay the foundation for subsequent transactions.
2. The young songbird crows for the first time
After a long-term historical low, when the chips reached the pre-allocation part of the funds, the main force began trial operation.
With a small amount of money to buy the stock price up ... But because the stock price has been at a historical low for a long time, it has formed a habitual mindset of retail investors.
As soon as the stock price rose slightly, the floating code soared immediately. Because the main force has not cultivated the follow-up disk, it will drop a long shadow line on the daily K-line.
3, the golden needle bottomed out
This test method is completely opposite to the first crow of the young warbler, which is to pull up, test the upward pressure and sell;
On the other hand, the bottom of the lily is just the opposite. It is to use the chips in hand to suppress the stock price and test the ability of the next file and the stability of the chips in the hands of the original investors.
Because it is easy to attract investors' attention and follow the trend by adopting the method of young warbler crying first, when the market rises after the day, it is easy to cause too many low-level follow-up orders, and the profitable customers actually flee, resulting in the passive rise of the main force.
However, the bottom of the lily evaded the above risks and took measures to suppress it downward. Instead, I picked up a batch of panic cheap chips before the rise.
"Ant on the tree" form
"Ants on the tree", also called "irresistible", is a K-line technical form with high possibility of individual stocks going cattle. Generally appears in the bottom area of the stock price, which is a sign that the stock price has bottomed out and started to strengthen.
The core point is that the small and medium-sized Yangxian line advances slowly, and then the big Yangxian line (preferably the daily limit) breaks through the midline form.
In the trend, the stock price tends to be stable after a long-term contraction and decline. When the stock price stepped on the 13 moving average, it rose slowly with a small rising line (not less than five), and the stock price was gently sent to the 55-day moving average. This is called ant climbing the tree.
Due to the long-term shrinkage and decline of stocks, the energy of shorting has been exhausted. At this time, the main force has completed the opening of positions, and once the index cooperates, it may rise at any time.
In order not to attract the attention of the market, dealers are still buying at a planned price limit. The purpose of this is to test the disk surface and preheat it before pulling it up.
Therefore, we should attach great importance to individual investors who form the form of ants climbing trees. Once you find an upward trend, you should follow up immediately without hesitation!
morphological character
1, the transaction volume is very small;
2. Xiaoyang Line is advancing slowly;
3. The stock price is in the bottom rebound trend;
4, 5 o'clock above the Dayang line, with more than 3 times the volume;
5. The short line group passes through the middle line group, and the middle line group is flat and upturned;
The best time to buy "ants climbing trees";
1, the first or second negative line of stock price correction, light warehouse exploration.
2. You can pay close attention to the day when ants climb trees and successfully break through the 10 moving average.
3. The stock price forms a trend of "Yang Ke Yin", that is, if one Yang eats a few Yinxian or a Yinxian a few days ago, he can attack half or heavy positions.
