Separate the decision from the outcome
A trade can be a good decision and still lose. It can be a bad decision and still win. If you judge decisions by results alone, you'll learn the wrong lessons: that the random entry without a stop was fine because it worked this time. Good decision making starts with judging trades by whether they followed a sound process.
A pre-trade checklist
Pilots and surgeons use checklists because even experts skip steps under pressure. A short trading checklist does the same job. Tick every line before an order goes in:
- This is one of my written setups.
- It's inside my trading session.
- No high-impact news in the next 15 minutes.
- Stop loss is placed where the idea is proven wrong.
- Lot size comes from my risk rule, checked with a calculator.
- On a prop firm account: margin stays under the limit and the daily loss room covers my stop.
- I have not hit my daily loss or trade limit.
If one box stays empty, there's no trade. That rule alone removes most impulsive entries.
The flat test
For trades you're already in, ask: "If I had no position right now, would I open this trade at this price, with this stop and target?" If the answer is no, holding the trade is a decision you wouldn't make fresh. It usually means hope, not analysis, is keeping it open.
Plan decisions before the market forces them
Decisions made in the heat of a fast move are the worst ones. Plan common situations in advance:
- If price hits 1R in profit, then I move the stop to break-even or I don't. Decide which, once.
- If high-impact news is coming while I'm in a trade, then I close, reduce or hold. Decide which, once.
- If price gaps past my stop, then I accept the fill and don't re-enter for 30 minutes.
Think in probabilities
No setup wins every time. Instead of asking "will this trade win?", ask "if I took this exact setup 100 times, would the total be positive?" That question moves your attention from one trade to your process, which is where your control is.
Keep a decision journal
Next to each trade, write one line on why you took it and how confident you were, before you know the result. Later, compare your reasons with outcomes. You'll find some reasons that sound good but don't hold up, such as "it had fallen a lot, so it had to bounce", and those are the ones to drop.
Review process first
At the end of the week, sort trades into four groups:
| Won | Lost | |
|---|---|---|
| Followed the process | Good decision, good result | Good decision, bad luck |
| Broke the process | Bad decision, good luck | Bad decision, deserved result |
Work on the bottom row. The "bad decision, good luck" trades are the most dangerous, because they teach you to repeat mistakes.
