Subscribe to RSS feed StocksCafe Playground - Leveraging on StocksCafe API

By evankoh posted on 3 Mar 2019  -  11,653 views




Short Story
We now have an open source project aim at educating/sharing on how to use StocksCafe API. You can literally build any feature that you want! Simply go to this GitHub page to learn about all the awesome stuff you can do with StocksCafe API (such as generating and customizing the above graph easily).

Full Story
The ability to access StocksCafe through API was released a couple of months ago. However, there are very few users who are actually leveraging on this powerful way of using StocksCafe. I assume it is due to the lack of experience dealing with APIs and programming and hence not knowing the possibilities. Therefore, I have decided to open up a series of tutorials to demonstrate all the awesome things you can do with StocksCafe API (even if you have little to no programming experience).

1) If you want to perform technical analysis/investing
(Tutorial: Plot a moving average graph)

StocksCafe currently has limited features that supports investors interested in technical analysis. Of course, StocksCafe can try to build it, but it will never be as customizable/powerful as giving you the ability to program whatever indicator and set whatever parameter you want.

This is actually also my personal motivation of doing this. I generally use fundamental indicators combined with modern portfolio theory to manage my portfolio. However, it does not tell me whether it is a relatively good timing to buy/sell. Although I am not a strong believer or user of technical analysis (yet), I would like to think that doing some technical analysis is better than going in blindly or simply basing it on 'my current feel' for the stock/market.

And as always, if I am going to build it, why not share it!

2) If you would like to have more fancy/customizable ways of analyzing your portfolio
(Tutorial: View monthly dividends collected for your portfolio)

Even though there are already many ways to analyze your portfolio in StocksCafe, it is never enough, as I still receive suggestions on what else we can do. Now, you will no longer have to be limited by me and can simply access your own portfolio data and run analysis or build fancy graphs on them.

3) If there is a feature you want that is not in StocksCafe
With direct access to the same data that StocksCafe has, you will no longer be limited by features provided by StocksCafe. The only limit is your own imagination! (maybe programming skills :)

However, please do not be afraid even if you do not have any programming experience. Python is an easy-to-learn and modern programming language. Furthermore, the programming knowledge needed to perform standard analysis or basic graphing are often minimal and easily google-able.

How do I get started?
Simply follow this quick start guide. You have the option to either run it on the web or run it on your computer. If you just want to quickly mess around, running it on the web is recommended since there is no installation required by you. However, if you want to really leverage on StocksCafe API, I highly recommend installing it and running it on your desktop.

How can I contribute?
If you have done up a cool analysis or graph and would like to share them, please feel free to make pull requests (if you do not know how to do this, simply send your code to Evan). Contributions are highly appreciated!

What's next?
I will be adding more indicators, graphs, and also build a backtesting system to test out indicators and investing strategies.

Happy programming and investing!

angelzsoul - hi, for the option of running on the web for the file "Plot Moving Average Chart.ipynb",
after changing StocksCafeApi(apiUser='YOUR_USERNAME', apiUserKey='YOUR_API_KEY')

do we need to edit it back to StocksCafeApi() and save it?
Just wondering if the system will autosave and store our API online

Thanks!

"do we need to edit it back to StocksCafeApi() and save it?" => No, you do not need to edit it back and save it. It cannot be saved.
"Just wondering if the system will autosave and store our API online" => These remote machine are temporary. You cannot store anything on it. However, technically, there is a way to push information back to GitHub (You need to fork my repo and have your own repo though) BUT it is strongly discouraged by them (https://mybinder.readthedocs.io/en/latest/faq.html#can-i-push-data-from-my-binder-session-back-to-my-repository)

Coming Back Soon: Dividend Information and More
It has been two weeks since my last update. I am happy to share that most administrative issues with SGX and third party data providers have been handled. Next on the list would be to tackle the technical issues of integrating data that I have licensed into SGXcafe. I have already started integrating dividend information, since this is something numerous users have been asking me about. At this point ...

Start of Support for London Stock Exchange!
The current top request (i.e. the most likes) is for StocksCafe to support the London Stock Exchange (LSE), and I am very happy to share that StocksCafe now provides limited support for LSE! What does limited mean? It means that StocksCafe only has End of Day pricing data for LSE. We were unable to secure dividend nor fundamental data. However, with this, you can enter transactions for London stocks ...

Slow-loading Pages and Tracking StashAway
Slow-loading Pages If you have been using StocksCafe for the last few days, you might have experienced extremely slow loading of some of the pages on desktop. I apologize for the poor experience. It is likely due to the auto-completion feature (suggesting stocks as you type) that is available on some pages such as this and this. It is the combination of poor design of the auto-complete feature and ...
