Hello everyone 
I’ve managed to get 3rd release of my book out!
I guesstimate it to be about 75% finished and with 15 chapters, it’s 200+ pages long.
Newest release contains 3 additional chapters:
“Abstract duplicated supervision code” - we will venture into abstracting away the supervision logic that we copied in the previous chapters by leveraging refactoring and macros. This chapter contains a full refactoring session.
“Store trade events and orders inside the database” - we implement a new application that will be responsible for storing data from the PubSub topics. Additionally, we will look into how we could make the supervision tree even better by introducing Elixir Registry.
“Backtest trading strategy” - based on improvements from previous chapters we will be able to implement an extremely simple backtesting method that will stream trade events from the database to PubSub topic
I would like to say that I’m gratefully thankful for all the support from the Elixir community with this project(both book and videos) - I couldn’t do this without you 
Enjoy - now back to the videos
