PnL Book — trading journal that prices your mistakes

Your mistakes have a price. See it in ₹.

Your P&L already knows what you did wrong — PnL Book reads your trades from any broker screenshot, prices every broken rule in rupees, and coaches the psychology behind the numbers. Zerodha, Groww, Upstox, Angel One — ₹ native, IST native.

Import

The journal that fills itself in.

A screenshot of your broker's P&L page is enough. The AI reads every fill — symbol, quantity, entry, exit — flags low-confidence fields for your review, and skips duplicates automatically. Journaling that takes seconds, not an evening.

On Zerodha or Groww? Console and Groww CSV files import in one step, too.

Priced mistakes

Know what every mistake costs.

Tag the trades where you broke your own rules — FOMO entries, revenge trades, moved stop-losses — and PnL Book prices the habit in rupees. Not a lecture. A line item.

The tags take seconds. The totals are hard to argue with.

Trading psychology

A coach that reads your ledger, not the market.

Every Sunday, a letter: what worked, what leaked, and the process fixes for the week ahead — the revenge re-entry, the oversized Friday, the day you should have closed the terminal. Every claim cites your own numbers.

Never tips. Never signals. Never a view on tomorrow's market — only on yesterday's decisions.

Questions traders actually ask

Do you need my broker password?

No. PnL Book never connects to your broker account and never asks for credentials. You import trades from screenshots or CSV exports — that is the whole surface area.

Does it work with Upstox, Angel One or Dhan?

Yes. Screenshot import works with any broker app that shows a positions or P&L page. Direct CSV import currently covers Zerodha Console and Groww.

Is this investment advice?

No. PnL Book is a journal and analytics tool for trades you have already taken. It does not recommend what to buy or sell, does not predict prices, and does not send signals.

What happens if I stop paying?

After a short grace period your account moves to the Free plan. Nothing is deleted — your full ledger is retained, and you can pick Pro back up whenever you want.

Can I export my data?

Yes. Export your complete trade history as CSV whenever you like, on any plan — including Free.
