The five costliest mistakes
| Mistake | Typical outcome | Fix |
|---|---|---|
| No stop-loss | Unbounded loss | A mandatory stop on every trade |
| Oversized lot | Rapid blow-up | The 1–2% rule |
| Doubling after a loss | Accelerating losses | A daily loss limit |
| Moving the stop away | Loss larger than planned | Only ever move it in your favour |
| Entering on news | Slippage and wide spread | Stand aside or cut size |
Why moving your stop is worse than it looks
As price nears your stop, there is a strong pull to move it "just a little" to give the trade room. The problem is that this converts a calculated loss into an open-ended one.
Worse, it breaks the original logic: you placed the stop at a level that invalidates your idea, so if price reaches it the idea is genuinely finished. Moving it means you are now trading on hope rather than rules — the origin of most large losses.
The one acceptable exception: moving the stop in the direction of profit (locking in gains), never in the direction of loss.
Revenge trading
After a painful loss, many rush into a new trade immediately at a larger size to "win it back". That is not a strategy but an emotional reaction, and it usually produces a bigger loss.
The cure is simple and mechanical: a daily loss limit. On reaching 3–5% of the account, close the platform for the day however tempting the setup looks. The decision is made in advance while calm, not in the moment of frustration. See gold risk management.
Building immunity to these mistakes
- A written plan: entry, exit and risk conditions defined before you open the platform.
- A trade journal: record the reason for each trade and its outcome; you will find your errors repeat in one pattern.
- Weekly review: read the journal, identify your single most frequent mistake, and work only on that next week.
- Automatic limits: set stop and target at entry so the decision is not left to later emotion.
The successful trader is not the sharpest analyst but the one who sticks to their rules precisely when breaking them is most tempting.
