Built in India, for Indian F&O traders
FnoDiary is purpose-built for Nifty and BankNifty options traders on Dhan. Every feature — from live candle charts to discipline scoring — is designed around the way retail F&O traders in India actually trade.
Why we built this
Most trading journals on the market are either generic spreadsheets or expensive platforms built for US equity traders. Indian F&O traders have a completely different workflow — intraday options, Dhan as a broker, Nifty and BankNifty as the primary instruments.
We wanted a single place to pull live trade data from Dhan, see the actual option and index candles for each trade, score our own discipline, and write down what was going on in our head. Nothing like that existed, so we built it.
What we stand for
Discipline over luck
We built a scoring system that calls out revenge trading, overtrading and size doubling — because habits matter more than any single trade.
Psychology is the edge
A psychology journal is not optional — it is the core feature. Understanding your own patterns is the one edge that can't be arbitraged away.
Privacy first
Your trades and journal entries are yours alone. We do not sell data, run ads, or share anything with third parties. Ever.
Who we are
A small team of traders and developers
FnoDiary is an independent product — not VC-backed, not ad-supported. We are traders who code, building tools we use ourselves every day. That means we ship features that matter to actual F&O traders, not features that look good in a pitch deck.
Company details
What FnoDiary is not
We are not a broker, an investment advisor, or a signal provider. FnoDiary does not give buy/sell recommendations and is not registered with SEBI. The platform is purely a journaling and self-analysis tool — the analysis and decisions are always yours.
We also do not take custody of your funds or login credentials. Your Dhan access token is used only to read your own trade history and candle data — nothing else.
