Metric methodology
How does FillScope calculate R-multiple?
R-multiple expresses a trade result relative to the amount the trader recorded as initial risk.
What is the R-multiple formula?
R = FIFO realized P&L / initial risk. FillScope recalculates the field when initial risk is saved for a trade. The initial risk must be greater than zero. A positive realized result produces positive R; a loss produces negative R.
Where does initial risk come from?
Initial risk is a user-entered review field, not a value inferred from the Flex import. It should represent the monetary loss defined by the trader before the trade. If it is absent, zero, or entered after the fact without a reliable record, the R value is unavailable or less trustworthy.
How are R values summarized?
FillScope reports coverage, average R, total R, average winning R, and average losing R only from rows where R or initial risk is recorded. Coverage shows how much of the trade history has risk data; it is not a quality score.
What are the main limitations?
The current calculation uses the imported FIFO realized P&L field and the recorded initial-risk value. Currency conversion, partial closes, scale-ins, scale-outs, options multipliers, fees already reflected in the broker field, and the trader's definition of a “trade” can affect interpretation. Compare like-for-like records and inspect the source row before acting on a summary.
