How to write a formula for stock selection with high success rate?

Edit the technical requirements of stock selection into formulas according to logic. This is a quantitative process.

Technical quantification is conducive to stock selection, which is in line with the starting point of simplifying the complex. From the experience, it is best not to quantify the conditions, or try not to build on the established indicators (it is easy to make a mistake when editing the quantitative formula at present: trying to increase the success rate of stock selection by kneading and weighting many existing indicators). Because the index itself has a certain degree of error probability. When you build a new technology on an obviously uncertain basis, the error probability will further increase. Therefore, the formula editor should try to use the original and more radical technical theory.

In addition to technology, stock ups and downs also include (dynamic) emotions. In other words, it is unacceptable to try to select stocks in one step through the refinement and accuracy of the formula! Formula, still can only be used as the first step of stock selection. The complete stock selection model should be a solid technology (or formula), which is more close to the definite result after being screened out by artificial subjective analysis.

There are some stock selection formulas with high turnover rate, and I have compiled many, but they are basically oversold models, and there has been no theoretical breakthrough in the rising model.

First, oversold. The conditions for oversold are relatively simple. Take the 30 th and 60 th days, and the oversold is more than 25%, which can be used as the basic condition for selection.

The second is quantitative change, and long-term shrinkage combined with short-term heavy volume is the basic condition.

Third, the market, if the market does not oversold, oversold stocks are generally problem stocks, try not to participate.

The fourth is the basic conditions, such as circulation, performance and so on.

Combining all these conditions, a good stock selection formula can be compiled.

The essence of the high success rate stock selection program lies in the efficiency of your stock selection model, and the stock selection program only expresses the stock selection model in computer language.

In my experience of playing programming, there is hardly any efficient stock selection model, so it is difficult to realize the idea of solving all the problems in stock trading by programming (to be precise, I have been playing programming for so long, and I haven't found a solution to the problem, maybe it's just my own stupidity, or maybe another expert is unknown).

The benefits that programming can bring me are:

(1) You can select all the stocks that meet my technical requirements on that day by running the stock selection program, which improves the efficiency of stock selection. It is always more efficient to choose stocks in a screened stock pool than to rummage through more than 3000 stocks.

(2) Through the design of stock selection program, select stocks that meet certain technical requirements, and perceive the actual temperature of the stock market through the changes in the number of these stocks. For example, recently, technically, May 12 was the 34th trading day (time window) of the market rebound, which technically showed a peak, but I'm not sure this is the high point. On May 14, the results of my stock selection showed that the status of individual stocks began to deteriorate continuously, and there was no sign of improvement. Judging from this, the market entered an adjustment period and decisively began to lighten up.

(3) Programming skills, for technical schools, can help people who study stock trading technology to understand the effectiveness of various technical methods more quickly and efficiently. If you learn any technology, you can immediately write a program, select the stocks that meet the technical requirements, and then observe its trend to verify the effectiveness of the technology you have learned. In a word, programming can make us more efficient, but it can't solve all the problems we encounter in stock trading (don't laugh at me when you see it, I'm waiting for your advice, thank you! )

Buffett thinks the return on equity is the most important.

Generally, free stock picking software supports very little push, either spending money or being cracked by experts. Formula stock selection is mostly not selected under the full push market, and the success rate is not very high, which is normal! If you want to improve the success rate and meet certain index characteristics within minutes, it is recommended to choose the full push market. The success rate is very high, and there will be a short difference only after the market opens lower. It is not bad to improve the efficiency of stock selection through formulas! After proficiency, I can hardly use formulas, but I can quickly put them in my head!

Is the success rate of 85% high at three o'clock in three days? This indicator has no future function.

Stop loss 10%, take profit 20%. Since June 2000, the test success rate of 1 has been over 80%. Can it be used in actual combat?

Quantization of morphological trend > probability editing after quantification >; Combined programming. Used for early warning or independent stock selection. This is the so-called stock selection formula, and the most important step is probability editing, provided that there are accurate quantitative data.

You can see the signs by adding the K line to the moving average.

The bonding of moving averages diverged upward, breaking through the profiteering of stock selection, the demon stocks broke through the daily limit of stock selection, the black horse cattle stocks selected stocks, and large funds entered the market to select stocks.
