I find these solutions and platforms can be useless compared to coding your own. If you roll your own, you will be able to define and control your own trading techniques. You will understand them better so don’t be lazy. This does support Python though.
I am still hearing about those use this QuantRocket or something similar?
NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
