As a seasoned trader with five years of experience, one common mistake we often make when investing is setting our direction and targets in advance. When market conditions and news flow change, we still convince ourselves that it's just a pullback and not a risk. We must adhere to our trading discipline and rules. Only enter a trade when a signal appears. Exit when a signal appears. Everyone's indicator discipline is different; some look at moving averages, some at trend lines, some at Bollinger Bands. Some base their decisions on news flow. Or MACD—I think all of these are good. The biggest mistake is mindlessly setting take-profit and stop-loss levels and overleveraging, leaving no room for flexibility. Because the financial market is extremely risky, requiring high intelligence, strong physical stamina, and is the industry closest to money. It’s not gambling. Many novice investors completely misunderstand the true meaning of trading. It’s a battle between buyers and sellers, a contest of long and short positions. Ultimately, it’s about the volume of buying and selling within a unit of time, which causes the direction to change. I hope everyone prioritizes reducing positions, protecting capital, and taking profits. The most important thing is risk management, not mindless gambling.
