You can't. You can automate things probably but there are already better tools that are focused entirely on trading automation. Compared to them, ChatGPT will perform worse. These types of AI are prone to hallucination, you should in no circumstance use them for handling anything related to money.
Do professional traders rely on Chatgpt for large-scale, let alone daily, trades? I'm not sure, so I don't rely on this tool.
They don't, the risk is too large.
