Here are some tips for friends who are not very good at AI or haven't used AI yet.

1/ You can't be sure whether a certain strategy will make money. You might think that coding it would be a lot of work and too troublesome.
At this point, don't give up or feel it's too complicated. Spend a few hours letting AI help you create a simulation to run for a while. See if the theory is feasible.
Simulation is just theory. If the theory shows significant profit potential, then real trading won't be far off.
Writing a simulated trading system usually only takes a few hours. No matter what market you're in, the most time-consuming part is the real trading, but if it can make money, you'll be motivated to refine it gradually. Making money is the primary driving force.
2/ Many people stay at a superficial level of exploration. I even wonder, with AI, what am I supposed to do?
Start by familiarizing yourself with the basics. If you're good at arbitrage, do arbitrage. If you're good at scalp trading, do scalp trading.
The main goal is to learn how to get comfortable with AI. Once you reach a certain level, you'll realize it's a productivity-boosting tool. You'll have endless things to do.
You won't ask anymore, "What can I do with AI?" because there's nothing it can't do.
The more you use it and the deeper you go, the more things you'll want to accomplish.
