Implementing my first strategy in Zorro - from Dick Stoken's book "Survival of the fittest for investors"

I will be glad to hear feedback on any suggestions for improvements.

Main repo - https://github.com/alun/stoken-aca

Older version - https://gist.github.com/alun/4424cb0e61a4955355ea82bb72286af3

I had strategy in Python before - https://katlex.com/stoken/

Currently results are quite different (even with Reinvest = true) - I keep working to make both implementations as close as possible.
