I finally present to you Fenix version 1 !

After months of going through multiple broker API Documentation and trying to unify their JSON output. I finally have come at a point where I feel comfortable releasing it out into the open.

I highly recommend downloading or just "pip install fenix" from the terminal and provide me with some feedback.
