Create a cryptocurrency trading bot in Elixir
About the Book
THIS BOOK WAS SUPERSEDED BY THE OPEN SOURCE VERSION AT www.elixircryptobot.com, you can get PDF/EPUB versions there or read it online. Please consider supporting this book and my other work via the GitHub Sponsors program(it supports both one-off payments as well as “monthly” plans).
This book is a loosely written representation of Create a cryptocurrency trading bot in Elixir video course released on YouTube.
Its core feature complete and at this moment new content will be "add-ons" to what is already there like indicators.
The source code for this book together with errata (issues) is available at GitHub.
The video course is still an ongoing production and will be continued in the upcoming months(as of March 2021)
