How to Write a Trading Rulebook You Can Actually Use

You marked a level on XAUUSD before the London session. Price moves beyond it, and you feel like entering now. Your note says, “Wait for a good breakout.” But what does good mean while the candle is still open?

XAUUSD means gold priced in US dollars. A breakout means price moving past a level you marked. That move may continue or turn back. The point here is not to predict it. The point is to make your own decision rule clear before you feel pressure to act.

Quick answer: your trading rulebook is the short set of conditions you chose in advance: what you may trade, what must happen first, what makes a trade invalid, when you stop, and what you record afterward. It should be clear enough that you can tell whether you followed it, even when the trade wins.

First, separate the firm’s rules from your rules

If you trade a prop-firm account, your personal rulebook cannot replace the firm’s current terms. Open the official terms and dashboard for your exact firm, program, stage and account. Check how the firm measures losses and drawdown, or how far the account can fall. Check which trades or holding periods it restricts, whether news rules apply, and what it requires before a payout. Rules and outcomes can differ.

Write the relevant constraints in one place and note where and when you checked them. Do not copy a number from someone else’s account or assume that a missed condition is always a breach. The prop-firm rules guide shows what to check in the source.

Then write your own rules beneath those constraints. Your personal rules describe the setup you plan to take and how you will handle your decisions. They can be stricter than a firm limit, but they do not change the firm’s terms. A trading plan is the wider set of conditions for your trading; this rulebook is the part you want close enough to check and review.

If your rules allow you to move a stop or change an exit after you enter, write the exact condition in advance. That part is trade management, and it needs a record you can check later.

Turn one vague sentence into a checkable rule

“Only take good breakouts” leaves too much room to argue with yourself. In this fictional example, you are writing your own XAUUSD London breakout rule. It is an example of clear wording, not a setup recommendation:

My breakout rule, version 1: I consider this setup only during my planned London session. Before the session, I mark the level I will watch. I wait for the breakout candle to close beyond that level. Before any entry, I write where my stop loss would go and check the size using my own method. If the candle is still open, the setup has not passed my check.

A candle is one price bar for the time period you chose. A stop is the point your own plan uses to say the trade idea is no longer valid. The example gives no live entry, direction, target or risk amount. You must choose and test your own setup, and check it against your account’s current firm terms.

Now return to the opening moment. Price has moved beyond the level, but the candle has not closed. You might worry about missing the move. That feeling does not make the rule wrong or the trade right. In this example, the written confirmation is incomplete. An entry now would change the plan you wrote. Waiting does not mean you must trade after the candle closes; the other conditions still need to be checked.

This is rule-based trading: you compare the decision with conditions written earlier. Whether a trade matches your named setup is setup compliance. Neither term means that a matching trade must win.

Keep the usable rulebook short

You do not need to squeeze every firm document and trading note onto one sheet. Keep a one-page core you can actually look at; store full official terms and detailed research separately. Here is a copyable starting point. Fill in the blanks with your tested plan and verified account terms:

My rulebook — version / date: ____
Firm, program, stage, account and official terms checked on: ____
Market and planned session: ____
Named setup and required checks before entry: ____
My size method and personal stop condition: ____
What makes this trade invalid: ____
What I record after the decision: ____

The fictional breakout rule above fills the named setup and required checks line. Its invalid condition is simple: the candle has not closed, or another required check is missing. It does not fill in a firm’s limits for you.

Before the session, a pre-market routine is simply your planned check of the coming session and your own rules. If you want a shorter set of boxes to use at the decision moment, use the trading-discipline checklist. That checklist is the quick-use version; this page helps you write the rules behind it.

Record the decision separately from the dollars

Your journal can keep four small facts together: rule version, what the rule required, what you did, and net profit or loss (P&L). For example, two separate fictional XAUUSD records could say:

• Record A: The candle had not closed. You entered anyway. The trade ended +$28 net. Rule followed? No.
• Record B: The required checks were complete before your entry. The trade ended −$22 net. Rule followed? Yes.

These amounts are example outcomes, not suggested risk or targets. A profit does not erase the early entry. A loss does not prove that a rule-following decision was wrong. Keep both facts so your later review is honest. The prop-firm trading journal explains the fuller record.

Change a rule after review, not to excuse a trade

You may learn that your rule is unclear or hard to use. That is a reason to review it, not to quietly rewrite what an earlier trade meant. Keep the version and date beside each journal record. At a planned review, look for a repeated problem, write why you changed a rule, and use the new version from then on. One loss or one profitable rule break is not enough to prove that a different rule will work better.

If you notice repeated early entries, ask whether the candle-close wording was visible when you needed it and whether your records show the same mistake more than once. If you need the broader plan → check → record → review process, read trading discipline for prop-firm traders.

PropLogAI lets you manually record trade details, notes, emotions and whether you followed your own rules, then review those records. It does not check live orders, enforce your rulebook, decide your firm’s official status or promise a better result.

Your next step is small: take one vague line in your own plan. Write what you must see before the decision, what would make it invalid, and what you will record afterward. Then check whether you can use that sentence without arguing with yourself in the moment.
