Consider to provide an API in safer languages - e.g. OCaml

While Python is fast to prototype something with, it is hardly a language you can trust your money. It is not uncommon to write applications in trading in:

• Java
• OCaml
• Julia

I personally would prefer OCaml among those, since the famous Jane Street and Bloomberg use it, there are some libraries you can be inspired with:

• https://www.youtube.com/watch?v=hKcOkWzj0_s - talk on trading with OCaml
• https://blog.janestreet.com/
• https://bitbucket.org/ogu/ibx - OCaml implementation of the Interactive Brokers TWS API
• More advanced example - Imandra:

Another option would be to support QuantConnect which provides the API in F# language:
