A good trade can still lose: judge the process, not the outcome
A loss feels like proof you did something wrong. Often you didn't. A trade can follow every rule and still lose, and a reckless one can win. Learning to tell them apart changes how you learn.
The myth
We learn from feedback. Touch a hot stove, it hurts, don't do it again. So when a trade loses, it seems natural to think the trade was a mistake. When it wins, it seems like a good one.
That's how most of life works. Trading is different, because each single result has a lot of luck in it.
What's actually true
One outcome says little
Think of a coin that lands heads 60% of the time. Betting heads is the right call. It still loses 4 times in 10. Losing one toss doesn't make heads the wrong call.
A trading rule works the same way. If it wins 45% of the time with a 2-to-1 target, then 55% of its trades lose, even when it's followed perfectly.
Judging by results has a name
Poker player and author Annie Duke calls this resulting: judging a decision by how it turned out instead of by how it was made. In Thinking in Bets (2018) she shows how it leads people to learn the wrong lessons from both wins and losses.
Good trades lose, bad trades win
| Followed the plan | Broke the plan | |
|---|---|---|
| Won | Good trade, good result | Bad trade, lucky result |
| Lost | Good trade, unlucky result | Bad trade, deserved result |
The dangerous box is "broke the plan, won." It teaches the wrong habit, and it feels great.
Example in units of risk: two traders take 20 trades. Trader A follows every rule: 9 wins at +2, 11 losses at −1 = +7 units. Trader B ignores the stop twice: 11 wins at +1.5, 7 losses at −1 and 2 losses at −6 = 16.5 − 7 − 12 = −2.5 units. B won more often. A made better trades. A math example, not a promise.
How to grade a trade fairly
After each trade, ask these 5 questions before looking at the result:
- Did the setup match my written rule?
- Was the stop where the idea is clearly wrong?
- Was the size correct for my 1% risk?
- Did I check the news calendar first?
- Did I manage it as planned, without moving the stop away?
Five yeses is a good trade, win or lose. Any no is a lesson, win or lose.
What to do instead
- Log "rule followed: yes/no" on every trade. See how to keep a trading journal.
- Review in batches of 20, not one at a time. Single trades are noise; groups show patterns.
- Track your rule-following rate as your main number in the early months.
- Celebrate a well-taken loss. It means the plan worked as designed.
- Ask better review questions. Our journaling prompts help.
Common follow-up mistakes
- Changing the rule after every loss. You'll never learn whether the rule works.
- Keeping a rule because of one big win. One win is as random as one loss.
- Using "process" as an excuse to never review the rule itself. After 50 to 100 trades, the results do tell you something.
- Beating yourself up after a planned loss. It was part of the plan. See how to handle a losing streak.

Questions
Can a good trade lose money?
Yes. A trade can follow every rule, with a sensible stop and size, and still lose. Every method has losing trades. What matters is how the rule behaves over many trades.
What is resulting in trading?
It's judging a decision only by its outcome. A lucky win gets called skill and a planned loss gets called a mistake. The idea comes from Annie Duke's book Thinking in Bets.
How do I know if my strategy is working?
Look at 50 to 100 trades where you followed the rules. Check the win rate, average win and average loss together. One trade, or even 10, can't tell you.
Should I review losing trades?
Review all trades, wins and losses, with the same questions. The goal is to find rule breaks, which can hide inside wins just as easily as losses.
