Why do I always fail to hold onto my profitable trades? This question hits the pain point for most traders.

In summary, there are mainly these points:

**Cost basis becomes a psychological shackles**. Once you see unrealized gains in your account, your mind starts calculating "Should I take profits now to secure them?" for fear that profits might vanish right before your eyes. Basically, it's a lack of trust in market fluctuations.

**Lack of a proper exit plan**. You plan carefully when entering, but when it comes to holding positions and closing, do you rely solely on gut feeling? Are there clear price targets, technical signals, or timeframes to guide you? Without them, exiting naturally becomes a gamble.

**The illusion of "getting rich overnight"**. This mindset pushes people to two extremes—either impulsively close positions at the first sign of profit, missing out on subsequent market moves; or hold on stubbornly when facing losses, eventually sinking deeper into the mire.

**Position size is too large to handle**. When your position is too big, even small fluctuations can make you uneasy. No matter how perfect your trading plan is, under this psychological pressure, it can easily collapse.
