Start with the observation
An opening range breaks. A short run reverses. Price returns to a level you have marked on the chart. Each describes something observable. Each can be the beginning of a trading idea.
A useful first step is to write down the observation precisely enough that another person can identify the same event. Which session? Which bars? Does a wick count, or does the bar need to close beyond the level?
That definition gives the discussion a common starting point.
Make the decisions visible
Consider an opening-range breakout. Define the range as the first 30 minutes of the regular session. Even with that definition settled, several decisions remain:
- Does the first touch outside the range qualify, or must a bar close outside it?
- Which price is used as the reference for entry?
- What ends the observation or trade?
- Can a second breakout count after the first one reverses?
- How are shortened sessions handled?
Two people can agree on the pattern and answer these questions differently. Their resulting trades can differ substantially.
Ask what a statistic measures
A pattern study might measure how far price moved after an event. A strategy test might measure what a specified entry and exit would have captured. An execution record adds what happened with actual orders.
Read each result with its definition beside it. “Price reached 2R” says something about the available excursion. It does not establish that a particular exit captured 2R.
Similarly, a win rate needs its average winning and losing outcomes to become useful context. The expectancy calculator makes that arithmetic explicit using your own assumptions.
Keep a useful trading note
A compact note can contain four things: the setup definition, the decision rules, the market context, and the outcome under those rules.
Separate what was known when the decision was made from what became apparent later. That makes the note useful when revisiting it, especially if the chart looks obvious in hindsight.
The aim is to make the reasoning inspectable. Start with one clearly defined question, then add detail when it changes the decision being studied.
