For traders
The trading journal that reads you as well as your trades.
Most journals track entries, stops, and R. Prism tracks entries, stops, R — and the state you were in when you took them. The weekly Mirror shows you the setups you trade well and the ones you only take when you're already losing.
Why traders
Because the trade log is only half the data.
Every trader keeps some kind of log. Most of them look like spreadsheets. They record what happened. None of them record the version of you that was at the desk when it happened.
Prism is built on the thesis that the state you trade in — sleep, mood, recency of loss, interpersonal conflict — is usually the variable that swings the week. Log the trade in a sentence. Log what else was true in a sentence. Prism draws the correlation for you at the end of the week.
What the Mirror surfaces
The setup you trade best, and the state you trade worst in.
By the end of the first month you can usually read two things off the Mirror: which setup has the highest hit-rate when you are well, and which setup is most dangerous when you are tilted. A lot of traders discover that their favourite setup is not the one they make the most on — it's the one they most often take when they're behind.
By month three, the correlation layer gets sharp. 'Your worst-performing days are the ones where you journal about sleep.' 'Your best Fridays are the ones where you took nothing on Thursday.' These are the kind of lines a prop firm risk manager would charge $500/seat/month to surface, if they could.
What you get
A behavioural moat around your own trading.
Every trader eventually edges out on skill. The ones who last are the ones who also know when not to trade. Prism gives you the signal for that — not as a rule, but as a pattern you notice before the market does.
It is also the most honest record you will ever keep of yourself as a trader. Used consistently, the archive is a forensic tool for every slump — 'what was different the last time I traded like this?' is a question the Mirror is specifically built to answer.
Common questions
Before you sign up.
Do I have to import my trades?
No. You can just journal — sentences about what you took and why, and about how you slept and felt. Prism correlates from the writing. If you also want to import a CSV of fills, the roadmap has that; today the heavy lift is the narrative layer.
How is this different from Edgewonk or Tradervue?
Those are P&L analytics. Prism is a behavioural journal that happens to cover trading. Most serious traders use both — analytics for the execution data, Prism for the thing analytics can't see.
Will Prism tell me whether to take a trade?
No. It is a reader, not an advisor. It shows you the pattern; you still make the call. That distinction is deliberate — we are not building a signal service.
Is my trade data shared with anyone?
Never. Zero-retention agreements with every processor (Anthropic, OpenAI, Supabase). Your trade log is between you and Prism. Delete is immediate.
