The most easily fallen into trap "golden rule" in trading is "let profits run." It sounds cool, as if simply holding onto your position tightly will bring continuous gains. But reality is often more brutal— for most individual traders who haven't established a comprehensive risk management system and lack execution ability, this becomes a disguised trap.

You need to understand the market's temperament. It will never move in a straight line upward; it always fluctuates— advancing further, then retreating two steps, then advancing again. Why do institutions dare to keep adding positions when they see floating profits? Because they have a substantial capital pool behind them and hedging tools to back them up. What about ordinary traders? As soon as they see their account turn green, they get impulsive and pour in more money, often ending up— precisely at the top of a pullback. Profits quickly shrink, the breakeven line is pushed upward, and instantly, their mindset blows up.

This is not to say you can't follow the trend, but certain conditions must be met: your trading system must be repeatedly refined and capable of stable operation under various market conditions. Before that, taking profits in time is not cowardice; it is the most basic protection for yourself. Money only truly belongs to you when it drops into your pocket.

Too many people always think one trade can change their life. Holding onto the impatience of short-term trading and trying to endure long-term fluctuations often ends badly. First, learn when to make a move, lock in your gains, and then patiently wait for the next opportunity. Only by surviving can you have the capital to talk about "let profits run."
