Không được thua

There is a very interesting paradox in human psychology:
After winning, we don’t become more rational.
We only become more reckless.

This is not your fault.
It’s a natural chemical reaction in the brain.
1. Dopamine after a win creates the illusion of “invincibility”
A winning trade releases a strong surge of dopamine, which makes you:
OverconfidentLess vigilantUnderestimate riskBelieve the market will keep behaving the same wayScience calls this the Winner’s Effect.The more you win, the higher the dopamine, the more impulsive your behavior becomes.
2. The brain classifies profits as “not real money”
According to Mental Accounting, the brain does not treat recent profits as real money.
So it’s easy to think:
“It’s just profit anyway. Losing it doesn’t matter.”
This leads to:
Entering trades too quicklyTaking excessive riskBreaking your own rules
That’s why many traders give back profits right after making them.
3. Recency Bias makes you believe “it went up, so it will keep going up”
The brain tends to assume that what just happened will continue to happen.
When the market is rising:
You don’t wait for a pullbackYou enter too earlyYou buy near the end of the trendAnd you get stopped out on the next correction
It’s not the market that makes you lose.
It’s cognitive bias.
4. After a win, self-control drops sharply
Behavioral studies show:
People who have just won have lower self-control than those who have just lost.
This results in:
Entering trades without fully checking signalsSkipping standard setupsIgnoring multi-timeframe analysisNot waiting for clean opportunities
At this point, you’re no longer trading with logic,
but with neurochemistry.
5. Same person, same setup — so why different outcomes?
The setup didn’t change.
The market didn’t get harder.
Your psychology changed.
After a loss, you’re cautious.
After a win, you become careless.
Consistency breaks the moment you think,
“I’m better now.”
So how do you avoid losing money after winning?
Here are three core principles grounded in psychology and behavioral science.
1. Reset your brain after every winning trade
Ask yourself:
If this were my first trade of the day, would I still take it?Does this setup fully follow my system?Am I following market signals or my excitement?
2. Wait for the market to pull back
Every impulse move needs rest.So does the trader.Not waiting for a pullback means voluntarily putting yourself into a high-risk zone.
3. Only trade valid setups — never trade emotions
Euphoria is not a trading signal.
It’s a signal to stay out.
Message:
Most traders don’t lose because they lack knowledge.They lose because they don’t understand how the brain pushes them into bad decisions.
A sustainable trader is not the smartest one.
It’s the one who controls dopamine, knows when to sit out,
and maintains consistency even after winning.
