Printable study note: After a big profit: 10 steps (one page, print or PDF)
The feeling
“Yes! +$400 on one trade. I’m reading this market perfectly today. Let’s go again, bigger this time. It’s not even my money now, it’s profit. One more and today is huge.”
That feeling is great. It is also the start of how many traders give their best day back.
The short answer
Greed after a win is the urge to push harder right after a big profit: bigger size, more trades, no target. The win makes you feel sharper than you are, and the profit feels like “free money” that is fine to risk. A few normal losses at the bigger size can then wipe out the win.
The fix is to decide before the session what you do after a big win, and to protect the profit with rules: no size increase, a give-back limit, a journal entry, and regular withdrawals.
Why your brain does it
- “House money” feels different. Richard Thaler and Eric Johnson described a house money effect (Management Science, 1990): after a gain, people tend to take more risk, as if the gain were not fully theirs. In your trading account, profit is your money. It spends the same as your deposit.
- One win feels like proof of skill. A big win is exciting, and excitement makes it feel like you have “read” the market. One trade proves very little. See overconfidence after a winning streak.
- The target suddenly feels too small. After a win, the planned target feels like leaving money on the table. So the next trade has no target, or a bigger one.
- Stopping feels like wasting a good day. “The market is moving, I’m on form.” But the market doesn’t know you just won.
A gold example: from +$400 to −$140
Example numbers, not a real trade. A $5,000 account. The plan size is 0.20 lot (20 oz, so every $1 move is $20).
- Trade 1, by the plan: gold moves $20 in her favour after a data release. +$400. A great trade.
- Trade 2, greed: she doubles to 0.40 lot. No real setup, just “momentum”. Gold moves $6 against her. −$240.
- Trade 3, “win it back”: now she goes to 0.60 lot. Gold moves $5 against her. −$300.
End of day: +$400 − $240 − $300 = −$140. Her best trade of the month, and the day is a loss.
Now the same two losing ideas at her plan size (0.20 lot): −$120 and −$100 = −$220. The day would end at +$180. Still not great, because trades 2 and 3 were not setups. If she had stopped after trade 1, the day would be +$400.
Notice the turn in trade 3. Greed after the win becomes revenge trading after the first loss. The two feelings often come as a pair.
Warning signs
- You raise your lot size right after a win, with no written rule for it.
- You remove or widen your target “because it’s running”.
- You take a trade that is not one of your setups, because “I’m on form”.
- You count the profit in what you’ll buy with it before the day is over.
- You keep trading past your normal session end because the day “is going well”.
Five fixes you can do today
- Write your “after a big win” rule before the session. For example: “If I reach +3R today, I stop” or “After a win bigger than 2R, I take a 30-minute break and write the journal entry before any new trade.” See daily profit target vs daily loss limit.
- No size increase for the next 10 trades. Size changes only in your weekly or monthly review, based on many trades, never on one.
- Use a give-back limit. If you keep trading after a good start, decide how much of the day’s profit you can give back, for example half. When the day’s profit falls to that line, you stop.
- Withdraw part of your profits on a schedule. Profit that has left the account can’t be given back. See paying yourself: withdrawing profits regularly.
- Check whether the win followed the plan. A win from a broken rule is a warning, not a skill. Grade it honestly: grade decisions, not outcomes.

Your rule card
My “after a win” rules
- ☐ After a win bigger than ____ R, I take a break and write the journal entry first.
- ☐ I stop for the day at +____ R, or I keep trading only at the same or smaller size.
- ☐ My give-back limit: if today’s profit falls to ____, I stop.
- ☐ No size increase for 10 trades after a big win.
- ☐ I withdraw ____ % of profits every month.
What a good day should look like
A good day is not the biggest number. It is a day where:
- every trade was one of your setups;
- every trade used your normal size;
- you stopped by your rule, not by your mood;
- the journal entry was written the same day.
A +2R day that ticks all four is a better day than a +6R day where you doubled your size and got lucky. The first one can be repeated for years. The second one usually can’t. When you look back over a month, count your “good days” by these four ticks, not by the money.
If you’ve already given a big win back
It happens to almost everyone once. Don’t try to win it back today; that’s how a give-back becomes a blown account. Close the platform. Write down the exact moment the plan changed: the trade where the size went up or the setup stopped being yours. That moment is the lesson. Tomorrow, start at your normal size, with your after-a-win rule written at the top of the journal page.
Common mistakes
- Thinking greed only means “holding too long”. It also means sizing up, trading more and dropping the plan after a win.
- Treating profit as “the market’s money”. It’s yours. Risk it by the same rules as your deposit.
- Raising the size after a win, then cutting it after a loss. That is size by mood. It turns a steady method into a random one.
- Celebrating while the platform is open. Close it first. Celebrate after.

Frequently asked questions
Why do I lose money after a big win?
After a big win, many traders feel the profit is ‘not really theirs yet’ or ‘house money’, so they take more risk with it. They also feel more confident than their method justifies. The result is bigger size, weaker setups and more trades, which can give the win back quickly.
How do I stop giving back my profits?
Decide before the session what happens after a big win: stop for the day, or keep trading at the same or smaller size with a limit on how much of the day’s profit you can give back. Do not raise your size because of one win. Withdraw part of your profits on a schedule.
Should I stop trading after a big win?
Many traders do, especially if the win was much bigger than usual. A short break, a journal entry and a review of whether the trade followed the plan protect the profit and the habit. Our after-profit checklist gives ten steps you can print.
What is 'house money' in trading?
It is the feeling that money you just won is not really yours, so it is fine to risk it. Researchers Richard Thaler and Eric Johnson described this ‘house money effect’ in 1990. In trading, profit in your account is your money, just like your deposit.
Is it greedy to want bigger profits?
Wanting to grow is normal. Greed in trading means changing your plan because of a feeling: bigger size, no target, extra trades. Growing size slowly, by a rule written in advance and based on many trades, is not greed.
