Hello, I can work on your project and develop your system using Java or Python. I have already developed a system for a client who was using zerodha broker APIs. Rest details we can discuss over chat. I have also developed a open source python script to fetch Option chain data from NSE at regular interval and process it to generate signal and send notification in a free telegram channel, ping to get details.
I have more than 11 years of experience in Java development and couple of years in python development.
