Crypto trading bot

I am a newbie in Python. My goal is to create a crypto trading bot. All my users data is stored in SQL server db like exchange, api key, api secret, password etc.
I have to fetch those users from db and trade according to user info on their exchange.
I am receiving signals from tradingview
How could I start it? From scratch? Or there is any open source for this on GitHub?
I have to store all trading data in db like trades done with pnl, running trades etc to show to individual clients
Kindly guide me
