Most trading journals ask you to log every trade and tag how you felt. Most traders stop within a month. SubTrades starts from the tradebook your broker already produced, finds the behaviour that cost you money, and prices it in rupees.
SEBI's study of individual equity F&O traders found that 89 in 100 made a net loss in FY 2021-22. The usual explanation offered is strategy. The tradebooks say otherwise. What separates a losing month from a flat one is rarely the setup, it is what happened in the minutes after a stop-out, or the size taken after three green days.
Journals built for US equity traders do not fit that reality. They assume dollar P&L, an eastern-time session, monthly expiries and share-based sizing. An Indian options buyer trades weekly expiries with lot-based sizing on premium that decays fastest in exactly the sessions where the emotional pressure is highest. SubTrades was built around that, not adapted to it.
Three steps, and only the first one needs you.
Two ways in. API sync means you never touch a file. CSV upload means one export carries your full history.
Seven behavioural patterns, each detected from your own trades and each with the fix that applies to it.
A spreadsheet is free and flexible, and for some traders it is genuinely enough. The honest comparison is about what each one actually costs you in effort and what it can see.
| Spreadsheet | SubTrades | |
|---|---|---|
| Getting trades in | Manual entry, or a CSV you reformat each time | API sync, or upload the broker file unchanged |
| Effort per day | Grows with trade count | About 15 minutes, flat |
| Behaviour detection | Only what you thought to record | Inferred from timestamps, sizes and sequences |
| Honesty of the record | Written after the fact, from memory | The broker's own record, written as it happened |
| Cost | Free | Free plan, or ₹349 to ₹499 a month for Pro |
| Best for | Low trade counts and custom metrics | Finding behaviour you did not know was there |
Your first month of Pro is free, with no card. Because there is no card on file, nothing charges automatically: at the end of it you move to the Free plan unless you choose to subscribe. The Free plan is free forever.
Pro is ₹499 a month, or ₹2,799 a year, all prices including GST. Journal consistently and coins hold it at ₹349 instead. The discount rewards the habit the product exists to build, which is why it is earned rather than given. Full detail on the pricing page.
A trading journal is a record of the trades you took and the reasoning behind them, kept so you can review your own decisions rather than only your profit and loss. A traditional journal is written by hand after each session. SubTrades reads your broker tradebook instead, so the record is complete and objective, and adds the reasoning layer on top through a short daily review.
Five. Dhan and Groww connect over the broker API and sync automatically, so nothing needs uploading. Dhan syncs past history and the current day; the Groww API returns the current day only. Zerodha, Upstox and Angel One import by uploading your tradebook CSV, which contains your full history in one file.
No. Tagging is the reason most journals get abandoned within three weeks. Every pattern SubTrades reports is inferred from data already in your tradebook: timestamps, position sizes, sequences and P&L. You never label a trade as revenge or FOMO yourself.
Yes, twice over. Your first month of Pro is free with no card, so nothing charges automatically at the end of it: you simply move to the Free plan unless you decide to subscribe. The Free plan itself is free forever and includes unlimited journaling and uploads, the last 30 days of history, your calendar and equity curve, daily check-ins with streaks, and revenge-pattern detection. Pro is ₹499 a month and unlocks all seven patterns plus full history.
By journaling consistently. Showing up regularly earns coins, and those coins hold Pro at ₹349 instead of ₹499. Stop journaling and the price returns to ₹499. That is deliberate rather than a gimmick: the discount rewards the habit the product exists to build, so the lower price is always earned.
No. Pattern detection is algorithmic and runs across your whole trade history: timestamps, sizes, sequences, hold times and P&L. There is no per-query credit allowance, so no part of your history goes unanalysed because you ran out. AI is used for the coaching and journaling conversation on top of the detection, not to find the patterns.
Yes, and it is the primary use case. SubTrades understands NSE and BSE options contract naming, weekly expiries, lot-based position sizing and premium-based P&L. The patterns it detects, such as averaging into a losing option or holding a decaying position on hope, are specific to how options actually lose money rather than borrowed from equity trading.
About 15 minutes. The trade record itself is automatic, so the time goes into a short guided review rather than data entry. That constraint shaped the product: a journal that takes an hour does not survive contact with a job and a family.
Your trades and notes are private and are never sold. Broker connections are read-only: SubTrades can read your trade history and cannot place orders or access funds. You can delete your data at any time. SubTrades follows India's DPDP requirements.
Connect a broker or upload one tradebook. Your patterns surface on day one, with no tagging and no card.
