What is why journaling works?
Writing the reason at the moment of the decision is the only way to audit it later.

Why journaling works, explained
Memory rewrites a trade to fit its outcome — a lucky win becomes skill, a disciplined loss becomes a mistake. A note written at entry or at the close is fixed in time, so months later you are reading what you actually thought rather than what you would prefer to have thought.
A worked example
Entry note: “Held this level three times, stop under the last low.” Weeks later you can sort your closes by whether a thesis was written at all, and read the difference.
Where why journaling works shows up in a journal
A trading journal is where this stops being a definition and becomes your own number. sizeforzero computes it from the trades you import or log, alongside the rest of your analytics vocabulary, and every figure in the app carries an (i) that explains it in the same plain English you just read.
