Since the beginning of 2013, my focus has been on two points, one is the stock, the other is the mobile front-end and big data technology. The development of Internet finance will make Internet securities more and more hot, of course, I also hope to Combine these concerns and do something.
Now, my APP and WeChat public account are online. Every day after work, I spend more than an hour on their development. Every day during the day I basically think about how to improve, improve, and what meaningful new things can be done. Function, and then write the code at night. During this period, there were not only technical supplements, but also some knowledge supplements for stock market investment. My wife said that I was already in a state of jeopardy, and I was not in the state when I went shopping with her. .
With the understanding of stock investment, the function of my APP is always adjusted, and finally made things that do not look like the original design.
My app is called Slow Bull Stock, and it is now on the application market. The front-end is made by Sencha Touch + Cordova. Sencha Touch is based on ExtJS, and charts such as K-chart are made by Secha. At the same time, it integrates the sharing and micro community Other components, HTML5-based applications have more problems and the biggest performance problems, so the final app is still small and beautiful, the UI is as simple as possible. Of course, the performance on the low-end models is still poor, and subsequent new features are not based on Sencha Touch. Now, use the new pop-up WebView instead. The page uses AngularJs + Ionic + Zepto for single-page applications, and the K-line diagrams are changed to D3.
The three pictures below are three versions. At the beginning, the design was large and comprehensive. It wanted to cover all aspects of the stock app, and even thought about the docking trading system. It was a bit scary. . .
The second and third versions pursue small and beautiful, because the sliding of secha touch is a bit stuck, and it has been changed to the tab mode. The function only provides optional, periodic, discovery, and message. There is a list of functions in the discovery. Each function is A data product.
There are many stock APPs. It is unrealistic to do better than big wisdom and flush. I can only pursue my own personality. After researching the stock market investment, I found that all investment is actually in the investment cycle, whether it is the property market or the stock market. , Each has its own cycle. Mastering the law of this cycle is one of the things we want to learn, so at the end of my APP development, I hope he is an APP that manages the cycle. The three small boxes are the corresponding day. According to the idea of Slow Bull, the short cycle obeys the long cycle. The monthly line is green and is not suitable for entering the market. Each technical indicator has its own daily weekly and monthly trend. In addition, there is no information. Slow Bull is more Focusing on technology, the backstage has made a technical analysis platform that can build more technical indicators to help users choose stocks and see trends.
After the stock app went online, it was maintained and perfected for half a year, and there was no big promotion. There were 20 or 30 downloads per day. There were often 70 or 80 downloads. There was a promotion on the Encyclopedia of Encyclopedia. Heavy volume, it seems that there are so many users in Encyclopedia. Later, because it caught up with the stock market crash, it could not be promoted. The market had to adjust for a long time, and it could only wait for the cycle to improve. It took months or even years ...
After the APP is basically stable, I developed the WeChat public account. The function of the public account is similar to the APP, which is a subset of the APP. It is equivalent to redoing the function of the APP and adding some new functions, such as manipulation exercises. Trend simulation, spent about three months of spare time, developed using Angularjs + ionic + zepto + D3. Compared with the APP, the public account pays more attention to content subscription. The WeChat public account is very good and powerful. Before a fellow At Tencent, I now work together as a partner. He helped me with the backstage part of the public account. My brother was my senior when I participated in the competition at the university. He was the captain at the time and was fortunate to have his support. Thank you very much!
Because I have learned D3 technology, I have better and better control of charts. I have made several chart-based functions, and also created a promotion page. By simulating the big bull market, let users manipulate the market and see how much they can earn. If you are interested, you can use WeChat to scan the QR code below to experience this similar game. The data in it is the data of this year, three, four, five, and June. Remember to click on the buy and sell operations!
