Conviction & thesis
What is thesis?
The one-or-two-sentence reason you took a trade.
Definition
The one-or-two-sentence reason you took a trade.
Thesis, explained
A good thesis says what you saw, what would invalidate it, and where you’d cut. Writing it down before entry forces clarity and gives you something to grade later. Without it, post-trade review becomes guesswork.
Where thesis 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.
