The wedge
Their AI tags your trade. Ours reads what you wrote.
The same losing trade, two readings. One stops at the number. The other reads the human who wrote the note.

What sizeforzero reads
“Tape went dead after the open, got bored, doubled in to feel something.”
From sizeforzero: This is the third Friday you’ve sized up out of boredom, not conviction.

Sunday letter — sample
The losses this week share a tell — each one came right after a red morning, sized up while the first trade was still stinging. The note you wrote on the worst of them said it plainly: “want it back.”
A sample letter — not generated from real data. Yours is written from your own trades.

They built the journal people abandon. We built the one people keep.
Not 100 reports you’ll never open. The handful that earn their keep when you re-read them next year.
A month, at a glance
Green when you closed in the green, red when you didn’t. Click any day to drill into every trade you closed that day.
Three figures, not a hundred
Win rate, profit factor, and closed-trade volume — the exact triad the Reflect page renders. No composite grade, no false-equivalence score; just the inputs your eyes can read.
Every trade, with intent
Thesis and a note on every execution — captured the moment you take or close the trade, not in a separate ritual you forget. Your reflections live where they happened.
Reliability
Your trades land right the first time — and stay right.
Native broker sync is on the way. Today, import is CSV — and we’ve spent release after release making CSV import correct: every trade lands once, no phantoms, no miscounts. Your data leaves whenever you want — full CSV export, no lock-in.

From the founder
Built solo by Dhruv in Scarborough, ON. No VC, no investors, no data sale ever.
We’re early. There are no testimonials here yet because we won’t invent them — and we won’t quote a trader who didn’t say it. If you switch, you’re among the first, and your feedback shapes what ships next.
