Fear, greed and FOMO: the two forces behind most trading mistakes
- How fear and greed show up in real trading decisions
- What FOMO is, and why "missing" a trade costs nothing
- Practical habits that keep emotions out of the order button
Your brain wasn't built for trading
Trading puts money, uncertainty and speed together, the exact mix that makes people act on emotion. Two forces drive most mistakes: fear (of losing, of being wrong) and greed (wanting more, faster). Neither makes you a bad trader. Not noticing them does.
What fear looks like
- Closing a winner at +5 pips "before it turns", then watching it run to the target.
- Skipping a valid setup because the last two trades lost.
- Moving the stop loss further away, because taking the loss feels worse than risking more.
Research on decision-making (Kahneman and Tversky's work on loss aversion) found that a loss feels roughly twice as strong as a gain of the same size. That's why cutting winners early and holding losers feels natural, and why it slowly destroys the risk–reward from lesson 6.
What greed looks like
- Doubling the lot size after a few wins, because "it's working".
- Removing the take profit to "let it run" without any plan for it.
- Opening extra trades on the same idea, quietly multiplying the risk.
FOMO: the fear of missing out
A pair has just moved 80 pips without you. Social media is full of screenshots. You jump in, near the top, with no plan and a stop placed wherever. That's FOMO, and it combines both forces: greed for the move and fear of being left behind.
The cure is a simple truth: a missed trade costs nothing. A chased trade often costs a lot. There will be another setup tomorrow; there may not be another account.
Habits that help
- Decide before you click. Entry, stop, target and size are written down before the order, never during.
- Use if–then rules. "If price reaches my zone and the setup is there, then I enter. If not, I do nothing."
- Set alerts instead of watching every tick. Staring at the chart creates trades that aren't in your plan.
- Rate your emotion from 1 to 5 in your journal for every trade. After a month, look at results by emotion score. Most traders find their worst trades come at 4 and 5.
- Keep size fixed after wins and after losses. Change size only on a schedule, never on a feeling.
- Believing discipline means having no emotions. It means having a plan that works despite them.
- Changing the plan in the middle of a trade.
- Measuring a day by its profit instead of by whether you followed your rules.
