The original measure
The report module compared holding durations for positive and negative closed trades. The comparison depends on how partial fills, open positions, breakeven trades and timestamps are handled.
A worked example
An example sample with a median winning duration of 30 minutes and a median losing duration of 60 minutes has a ratio of two. That arithmetic does not explain why the trades differed or whether either exit was appropriate.
No exit rule follows
Instrument, strategy and market conditions may explain a difference; closed-trade selection can also exclude still-open positions. The display does not prove a disposition effect for a person or recommend profit targets, stop levels or exit timing.
