@hugobarauna, Dr. Dimitrios Koutmos (my brother) and I (Alex Koutmos) have been hard at work on writing a book on how you can use Elixir for analyzing financial data. This book leans on many of the latest computation-heavy libraries like Nx, Scholar and Explorer so you can analyze financial time series data. We also make extensive use of Livebook and Vega-Lite so that you can visualize your results. Livebook also makes it so that you can tie all these tools together and quickly build UIs to make the exploration of financial data more enjoyable!

Throughout this book you will learn how to:

Fetch and analyze real economic data from the FRED API
Pull down the latest stock market data from Yahoo! Finance
Calculate risk and return for your portfolio across stocks, crypto, and commodities
Build technical trading indicators and backtest them against actual market history
Map risk-return tradeoffs and evaluate portfolio diversification

By the end of the book, you will have a better understanding as to how the financial markets operate and how to analyze them your favorite programming language!

I too have a healthy dose of skepticism when it comes to these things lol. The reason it is a zip is because the free sample contains the epub, pdf, and Livebook notebooks and zipping it was the easiest way to distribute all the files in one bundle.

I just downloaded the free sample zip from ConvertKit to make sure they don’t stuff anything else in there. Everything in there is what we intended to bundle:

That sounds like fun!

While we don’t get into stream processing of data in this book, you can definitely apply what we teach you to stream processing time seriesy data. Not to mention, all the Nx tools and Explorer are wicked fast so you should have no problem appending data to a DataFrame for example and rerunning analysis .

I think need to add stream processing, your book in financial domain with machine learning is interesting. Do you have plan to publish on Pragprog.com ?

This sure looks like an awesome read. I did submit my email so that I can peruse through the free chapters before making a purchase decision but I’m yet to receive the free chapters bundle in my email. Isn’t this unusual? How else can I access the free bundle?

Got the beta and right now its not worth it. For me personally, price to elixir tricks value is much less compared to pragprog books. Hope final release will be better.

I definitely appreciate the candid feedback. Can you expand upon “price to elixir tricks value is much less compared…”? I’m not following what you mean by this?
