F&O Autopsy: where did options cost you?
Drop your broker's F&O tradebook. In a few seconds you see, in rupees, which kinds of option trades took your money - far out-of-the-money buys, expiry-day trades, time decay, volatility falling after events, STT and charges - and whether each pattern is real or could be chance. Your file is read on this device and never uploaded.
Zerodha Console tradebook, Upstox trade report, Angel One trade book, Groww order history, Dhan trade history, IBKR trades CSV. Other files with symbol, buy/sell, quantity and price columns usually work.
Add prices (optional, also read on this device)
We do not ship market prices. Positions you kept to expiry need their expiry price, and two checks need index closes. Add one or both:
- Your broker's expiry rows: the expiry-day contract note or P&L export lists every contract kept to expiry with its exchange settlement price (CSV).
- Official index history: download the CSV for your index and dates from NSE Indices historical data (SENSEX: BSE index archive).
No files? You can type the expiry-day close for each expiry the report asks for.

What it looks at
- Far out-of-the-money buys - options bought more than 2% away from the index, and what they returned.
- Expiry day - trades opened on the day the option expires, and bought options left to expire.
- Time decay and volatility - for options held overnight, how much of the result came from the index move, from time passing, and from volatility changing (for example after RBI, Budget, election results or US Fed days).
- STT and charges - estimated by trade date, compared with your winning trades.
- Size - your biggest loss against the account size you enter.
- Real or chance? - every group is checked against random groups of your own trades, so a pattern from a few lucky or unlucky trades is labelled as such.
Coming later
This check will look up past days with about the same days left and the same distance from the index, and show how often a trade like yours worked. It needs years of market prices, which we will only show once we hold a data licence.
Until then, the first tab checks your own trades with your own files.
The sample files are made up (invented prices). General information about your own past trades, not financial advice. Charges are estimates. We do not provide market prices: index closes and settlement prices come only from files you add or values you type.
