Let me share with everyone about the disruptive impact of quantitative trading and AI on trading. About a year ago, I started to look into this. In a nutshell: don’t let yourself be brainwashed by so-called quantitative trading into believing it’s a surefire way to win, and AI also can’t replace traders—especially not for trades within the medium-to-long term. It can only be used as an auxiliary tool. But if you’re interested in quantitative trading and optimistic about its future, if you want to learn, I can recommend a person: Xing Bu Xing on Bilibili. You can check out his videos and buy his course—it's only dozens or a few hundred yuan, I think. He’s currently the most authoritative one you can reach. I don’t personally know him—maybe I just couldn’t learn this stuff. If ordinary retail traders want to learn something, I suggest considering learning quantitative trading seriously and properly, instead of constantly thinking you already “get it.” Every line has a lot of learning behind it. When AI’s help in trading can be applied in real life, it will naturally end up in your hands—so you don’t need to learn it. Just keep learning and staying updated on how to use AI applications.
