The No-Trade Decision Tree for Paper-Trading Practice

Most paper-trading journals preserve the setups that became trades and lose the setups that were correctly rejected. That makes restraint invisible. This decision tree creates a short, reviewable record of why a hypothetical setup was stopped, revised, or allowed to move into a paper plan.

Three outcomes—not a trade signal

• STOP: a required input is missing, stale, or incompatible with the model. Do not invent a value to complete the worksheet.
• REVISE: the idea may be testable, but its thesis, invalidation, assumptions, or budget needs to be rewritten first.
• READY FOR A PAPER PLAN: every gate has an explicit answer. This means the plan is inspectable; it does not mean the trade is good or should be taken.

The eight-gate decision tree

1. Is the input data fit for the decision?

Write the timestamp and source of the price, spread, and any other input. If data is stale, missing, or measured on a different horizon from the idea, mark STOP.

2. Can the thesis be proved wrong?

Replace labels such as 'looks strong' with one observable if/then statement. Name a price or condition that would invalidate it. If no disconfirming observation exists, mark REVISE.

3. Does the sizing model fit the instrument?

A simple |entry − invalidation| formula only approximates linear per-unit exposure. Contract multipliers, leverage, currency conversion, non-linear payouts, and other instrument mechanics need an instrument-specific model. If the model is unclear, mark STOP.

4. Are execution assumptions written down?

Record estimated entry and exit costs plus the assumptions made about spread, slippage, gaps, and available liquidity. If the plan depends on a fill that cannot be reasonably simulated, mark STOP or build a more conservative paper scenario.

5. Is scheduled-event risk acknowledged?

Check whether a known announcement or market closure could change the execution assumptions during the planned window. The gate does not predict the event; it asks for a prewritten choice to exclude it, model it, or stop.

6. Was the hypothetical loss budget selected before the upside?

Write the practice loss limit before calculating a target or reward ratio. If the size was chosen to reach a desired gain, mark REVISE and rebuild it from downside assumptions. No percentage in this worksheet is a recommendation.

7. Does the whole-unit estimate fit inside that budget?

Use the appropriate model, include estimated round-trip costs, and round down where units are indivisible. If even one unit exceeds the selected budget, the paper plan has a valid answer: skip it.

8. Are you changing a rule because the setup is moving?

Compare the current fields with the first saved version. If entry, invalidation, or size changed only after seeing price movement, mark STOP, preserve both versions, and record the deviation.

A worked hypothetical

Suppose a practice account uses 10,000 of hypothetical equity and a preselected 0.4% loss limit. The loss budget is 40.00. A planned entry of 50.00, invalidation of 49.40, and estimated round-trip cost of 0.08 per unit creates estimated per-unit risk of 0.68. Rounding down, floor(40.00 ÷ 0.68) is 58 whole units, with estimated modeled risk of 39.44.

Now apply the tree. If the instrument has a contract multiplier that the calculation ignored, the correct result is STOP—not 58. If the input is a simple linear instrument but the spread estimate is missing, the result is also STOP until the assumption is made explicit. Correct arithmetic cannot repair a mismatched or incomplete model.

The three-minute skip record

• Timestamp and setup label.
• First failing gate and the observed evidence.
• Outcome: STOP, REVISE, or READY FOR A PAPER PLAN.
• What new information—if any—would justify another review.
• Whether any rule changed after price movement began.

Review skipped setups alongside completed paper trades. The purpose is not to prove that every skip avoided a loss; it is to test whether the decision rule was explicit and consistently applied.

Important limits

Paper trading cannot reproduce every live fill, liquidity constraint, gap, fee, tax, delay, or emotional response. This tree predicts no outcome, recommends no security or strategy, and does not select an appropriate risk level. It is general educational material, not financial, investment, legal, or tax advice.
