Price your mistakes. Fix your process. PnL Book is a trading journal built for Indian intraday & F&O traders.

Why PnL Book exists

Most traders lose money the same way twice — not because they lack a strategy, but because the same process mistakes go unmeasured. PnL Book turns your own trade history into a clear picture of what those mistakes actually cost you in rupees, so you can fix the process instead of chasing the next tip.

We don't sell tips, signals, or “sure-shot” calls. There's no Telegram pump group and no promise of returns. The only edge we help you build is a disciplined, data-backed review of your own trading.

What it does

  • Import in seconds — snap a screenshot of your broker order book and PnL Book reads the trades automatically (Zerodha and other Indian brokers).
  • Price every mistake — see the ₹ impact of overtrading, revenge trades, moving stops, oversizing, and holding losers, tagged and totalled.
  • Weekly AI coaching — a private, personalised review of your last week's numbers, with concrete, specific suggestions — never generic advice.
  • Journal & analytics — a calendar heat-map, streaks, win/loss breakdowns, and notes, so your review actually sticks.

Who builds it

PnL Book is a digital product of Quantmhill IT Services and Consultancy Private Limited (quantmhill.com), a technology company based in India. We're a small, focused team that trades, builds, and cares about getting the details right — from accurate P&L math to email that actually reaches your inbox.

Our principles

  • Your data is yours. We never sell it, and you can export or delete it anytime.
  • No hype. We measure process, not predictions.
  • Honest pricing. A free tier to start, and clear, cancel-anytime plans.
