I have recently come across an algorithmic trading platform that we can use with Kite connect API. The platform is still in its nascent stage. Creating a strategy is simple. At the same time some flexibility of using a programming language is lost. I made some money on this platform. One interesting feature is that with out sharing the source we can give it for deployment by other subscribers and earn money on that. It is a market place for algorithms. Another interesting feature is paper trading. We can test our strategy using paper trading configured as a broker. Of course limited back-testing is also available based on subscription level. Please check out the website here.
