Import your tradebook, find your actual edge, and see what your execution costs you — an India-first trading journal built on evidence, not stories.
Revenge, boredom and chase trades
−₹4,862 4 trades you graded “off plan”, 0% of them profitable.Record, analyse and improve — with Indian F&O charges, lot sizes and expiries understood.
Drop your Console tradebook. Fills pair into trades automatically, and re-uploads are dedup-safe.
Every figure is net of brokerage, STT, stamp and GST — modelled on Zerodha's rate card, and labelled an estimate.
Two verdicts, not one: does the setup pay, and do you actually follow it? The gap between them is the money.
Notes, tags, grades, planned risk and chart screenshots — on the trade and on the session.
“What if I'd skipped the C-grades?” Run it against your own book — never a simulation of someone else's.
Tag uploads per account and scope every screen. Fills never pair across accounts.
A digest of the week's edge, discipline and leaks, in your inbox.
IN BUILDTrade replay and MAE/MFE, on the chart your trade actually printed on.
NEEDS LICENSED DATAFalconn builds trading tools around one idea: decide from evidence, not from stories. Which is why nothing here is guessed — if a number needs data we don't have, the app says so instead of inventing it.
How we build →“What gets measured
can be improved.”
Different traders, different tools — the same refusal to show you a number we can't stand behind.
For retail F&O traders who want to know what actually works — and what their own execution costs them.
Our own algorithmic engine: research, validation and live execution under one evidence-first workflow.
Nobody is charged anything today. When that changes, it changes here first.
Everything the journal does today, free. No card, no sales calls.
The planned price once billing exists — beta users hear first and get a fair grandfathering. Until then, nobody is charged anything.
The desk trades our own capital. If that ever changes it will be announced here — loudly, with the regulatory homework done first.
We'd rather list what's coming than pad the page.
