One trade can move every average
With only three records, one large win can make win rate and average P/L look unusually strong. One normal stop can have the opposite effect.
Today Trade Journal fades comparison groups with fewer than three records to make the count visible. A group becoming fully visible does not mean it has completed statistical validation.
Match the definition before counting
If trades labeled breakout use different timeframes, entry conditions, and exit rules, a larger count still mixes different behaviors. Keep the tag and recording rule consistent first.
Inspect exceptional results separately
If one or two trades created most of the total, read the remainder as well. The exceptional result still belongs in the record, but it should not quietly stand in for the usual outcome.
Write an observation instead of a verdict
Recent losses were concentrated near the market open is more accurate than this strategy never works. An observation can be checked again as records grow, while a verdict tends to survive even when the data changes.
