I was chatting with some quantitative traders before, and I realized that one must abandon subjectivity (except for those who are exceptionally good at it) because most of them have been trading stocks for many years. If one cannot achieve stable profits based on subjective judgment, then it must be abandoned, as most people's subjective views do not make money. Today, I made a mistake: I saw the news and thought that gold's rise combined with the news meant a ceasefire, and that the Nasdaq's significant drop meant it was time to be bullish. This is purely subjective speculation, which led to losses. In reality, one should combine fundamental analysis, technical analysis, and capital flow, rather than making simple judgments based on perceived trends and news.
