Has anyone traded stocks before? If so, how did you learn to trade? Do programmers have any scope to write code for clients[Who are traders]? What about low code algorithmic trading platforms v/s Python?
Yes. Read a lot and try ideas on paper trading, then on small accounts. There is a small industry that helps traders to automation their strategy. Ninjatrader for example is one of the popular desktop trading platform while QuantConnect (C#) and Quantopian (python) are fully online environments to develop strategies. And there are many others.
