ZenBot - OpenSource flexible crypto trading bot
04 May 2017 · Last update 04 May 2017
There is a NodeJS bot available on GitHub - but it needs tweaking badly. You could either make a pull request or (probably better) fix the strategy and use it yourself, while the mundane work on the structure, middleware and UI was done by someone else.
Take a look at the commits here - https://github.com/carlos8f/zenbot/commits/master - Overfitting and BS much. However, the 4.x branch looks more hopeful.
Once again, don't use it without modifications.
