After mastering profitable trading strategies, why do you still frequently incur losses?

In fact, reliable strategies have long been discussed to exhaustion within the community. The real issue isn't the strategy itself, but the fact that fewer than 5% of people can stick to executing it consistently. Those who suffer losses are usually knocked back by these three hurdles—

**First hurdle: Execution failure**
The strategy clearly specifies stop-loss or take-profit levels. But when the moment comes, human nature kicks in. "Just a little longer, what if it rebounds?" "Hold on a bit more, maybe I can earn a bit more." In this way, you inject mental contamination into the strategy, and the final result is predictable.

**Second hurdle: Lack of patience**
The strategy says to wait for stabilization signals before entering. But most of the market time is chaotic. Those who can't wait start forcing trades, and what happens? Their principal is gradually eroded by fees and random fluctuations.

**Third hurdle: Misreading probabilities**
A positive expectancy strategy doesn't mean "never lose," but rather "lose less when you do, and earn more when you win." But many people start doubting the strategy after a few losing streaks, frequently changing strategies, and ultimately losing more as they go. That’s the real end of the game.
