Real calculation/methodology changes to /performance, in plain language, newest first. UI-only changes aren't listed here — only things that changed what a number on that page means or how it's computed.
Fixed a calculation bug where completed round-trips were incorrectly discounted by a fill-probability estimate meant only for forced-close exits — Net P&L % figures increased as a result.
Fixed pooled/combined statistics that were incorrectly summing percentages across pairs instead of properly weighting them.
