The direct answer: When a person intervenes instead of the plan.
The main real reasons:
Failure to secure profit
The price gives you clear profits, and you refuse to move the stop loss. The market does not forgive greed.
2. Greed after achieving the goal
The goal is achieved, but you say: “It may continue more.” Often here the reversal begins.
3. Breaking the technical rules you entered.
Did you enter at support? If the support is broken, the trade is over; previous profits do not matter.
4. Forcing the trade into an investment
A short speculative trade suddenly turns into 'long patience' without any technical reason.
5. Ignore the larger time frame
Profit is based on a small frame, but the overall trend is against you… the end is known.
6. There is no exit scenario
Whoever enters without an exit plan will end up with a loss even if they initially profit.
The harsh conclusion:
The trade does not betray you; you are the one betraying your plan.
