Rule-Based Trading

What is rule-based trading?

Rule-based trading means making decisions with conditions you wrote before the moment of action. The conditions should be clear enough to check later from your note, timestamp, screenshot or other record.

You can follow rules manually. Rule-based trading does not automatically mean algorithmic or fully automated trading.

Vague idea or checkable rule?

Vague idea: “XAUUSD looks strong.” You may understand the feeling in the moment, but the sentence does not tell you what evidence was required.

Checkable rule: “During my planned London session, the Asian high has broken, a candle has closed above it, and the retest meets the confirmation written in my plan.”

The second statement gives you facts to check. It still does not predict what price will do next.

A fictional six-step XAUUSD check

1. Is the instrument XAUUSD?
2. Is it the planned London-session window?
3. Has the Asian high broken?
4. Has a candle closed above the level?
5. Has the planned retest confirmation appeared?
6. Are the stop loss and position size set from the written USD risk before entry?

If a required condition is missing, the setup does not qualify under this trader's written rule. That statement checks the process. It is not a signal or a forecast.

Must every rule be yes or no?

Some rules are simple yes-or-no checks. Others need a written definition or an acceptable range. The aim is not to pretend that every judgment is mechanical. The aim is to make the decision clear enough for a later review.

How does it relate to a plan and setup compliance?

• Trading plan: the complete framework that contains the rules.
• Rule-based trading: using the predefined conditions while making the decision.
• Setup compliance: checking afterward whether the recorded trade matched those conditions.

A pre-market routine can help you prepare the conditions before the session. Your trading journal preserves what you wrote and what you actually did.

Can profit or loss tell you whether the rule was followed?

No. A winning early entry can still be marked rule not followed. A losing qualified setup can still be marked rule followed. The result and the rule check answer different questions.

Should you change the rule after entry?

Do not rewrite the earlier condition to make an open or completed trade appear valid. Record what was written before the trade. If you want to change the rule, do that separately after the trade or review period.

What should you do next?

Find one vague phrase in your own plan. Replace it with a condition you can check later from a note, timestamp or screenshot.
