One position, one review

Decide what one row represents before you count wins. An order is an instruction; a fill is an execution; a position can contain several entries and exits. Counting every fill as an independent completed trade can change the apparent sample without changing the economic result. Choose a consistent unit and document it.

For this course, use one completed example position per summary row, with its underlying fills kept separately. Include a position ID, instrument, direction, quantity, currency, entry and exit details, costs, net result, planned scenario risk, rule version and one observation. Label hypothetical, paper and actual historical records distinctly. Open positions should not quietly join a closed-position win-rate calculation.

Keep process notes separate from outcome. ‘Followed the written rule’ answers a different question from ‘made money.’ A rule-following loss can still reveal that the rule needs investigation; a profitable deviation is not proof that improvisation is a better method. The point of the journal is to make these questions visible, not to award yourself a favorable label after every result.
