I don't know why everyone likes the word "trader" so much and has always been a trader. Do you think this job is good or profitable? It's not as simple as you think. First of all, it is difficult to be a professional trader. There is also the problem of talent, of course, more of a problem of execution. Trading is a boring thing. When you want to build a trading system, you just need to keep executing-summarizing-modifying-during the execution cycle. After you improve, you just need to implement it. Isn't it boring to place an order mechanically?
