Write a setup rulebook
If the entry rule changes after every loss, you are testing a moving target. Write the rulebook before the sample begins.
Turn a chart idea into a complete, testable paper-trading decision.
A setup is a defined situation, not permission to buy whenever a chart feels promising. Specify the asset and venue, timeframe, observable conditions and the earliest moment the decision can be made. Someone else should be able to identify the same candidate.
Write entry, invalidation, planned exit and maximum cash risk together. Include fees, order type and a rule for a missed or partial fill. Define no-trade conditions such as missing data, excessive spread or an already reached session limit.
Freeze the rules before testing a sample. Record skipped candidates and losing examples as carefully as winners. If you change a rule after seeing results, label a new version and test it separately; otherwise the apparent improvement may simply fit the past.
Let’s use numbers · hypothetical example
For a fictional token, a paper plan buys 5 units at USD 20 only after a specified close. Invalidation is USD 19 and target USD 22: planned price loss USD 5 and gain USD 10, before costs. A gap can worsen the loss.
Keep in mind
The target ratio is not a forecast or proof of positive expectancy. The conditions may never produce a valid entry.
Your turn
Write a one-page rulebook and test whether two readers identify the same decisions on five covered charts.
A quick check before we move on
What if a required condition is missing?
- Change the rule after entering
- Skip or wait according to the written rules
- Enter because the target looks attractive
Check answer
Skip or wait according to the written rules A testable setup requires all predefined conditions. An attractive target cannot replace missing evidence.
