1. FOMO — Fear Of Missing Out
You see a stock running. You weren't in it. You feel left behind. You buy it 8% above your plan, exactly at the top, and watch it round-trip back down.
What's really happening: the survival brain hates being left out of the herd. The pain of watching others win feels worse than the risk of buying badly.
The fix: If a setup has already moved past your planned entry, the trade is gone. Wait for the next one. There are thousands of stocks; another setup is loading right now. Missing trades is part of the job. Not chasing is a profit center.
2. Revenge Trading
You take a loss. You're angry. You immediately re-enter — often bigger, on a worse setup — "to get it back." You lose more. You re-enter again. By the end of the day you've turned one $100 loss into a $700 loss.
What's really happening: the loss feels like an insult, and the brain wants to undo it right now. Speed and size both increase exactly when they should decrease.
The fix: Hard rule — after 3 losing trades in a single day, you are done. Close the platform, walk away, journal what happened. Tomorrow's market will be there.
3. Holding Losers, Cutting Winners
The most common pattern in retail trading. A winner is up 30% — you take profit "to be safe." A loser is down 15% — you hold because "it'll come back." You end up with small wins and big losses: negative expectancy, guaranteed.
What's really happening: the brain locks in the certainty of a small gain (to avoid regret) and avoids the certainty of a loss (to avoid pain) — the exact opposite of what math demands.
The fix: Define your exit before you enter. Stop = -1R. First target = +2R. Second = +3R. Mechanical. The plan removes the real-time emotional decision. Use the Risk Manager to set these levels before every trade.
4. Overtrading
You feel the need to "do something." Markets are quiet. You take a B+ setup, then a C+ setup, then a setup you'd normally laugh at. Each marginal trade has a marginal edge — but costs are real and your focus dilutes.
What's really happening: boredom and the belief that activity equals progress. In trading, the opposite is usually true.
The fix: Quality threshold rule. Only trade A+ setups. Some days you take zero trades — that's not failure, that's professionalism. The best days at the desk are often the no-trade days.
All four behaviors share one root: acting to relieve an emotion instead of executing a plan. Fix the root — pre-commit to rules — and all four shrink at once.
