What we do not do, and who does

01

Prove to others that your performance is real

If you want to prove to others that your performance is real, connect your account to a verified track-record service: it is free, it is continuous, and it is better than us. We read a file you upload to us; an uploaded file remains a self-declared document.

02

Declare your capital gains

If you want to declare your capital gains, a tax tool will do the job for a fraction of our price, and produce the forms. Our calculation conventions are measurement conventions: they are published so you can redo the calculation, not to serve a tax return.

03

Track your trades day by day

If you want to track your trades day by day and improve, a trading journal is made for that. We look at a closed past, not an ongoing practice.

04

See your balance

If you want to see your balance, your platform does that. It will not show you what it cost you.

The question we answer

We answer a different question, and only one

We answer a different question, and only one: what your activity actually produced — fees included, conversions included, compared with having done nothing — with whatever could not be measured written in the report.

The calculation runs in your browser: your file is sent nowhere, and your browser's Network tab shows it.
