Algo trading on NSE stocks and F&O, in your own broker account.
Nifty and BSE stocks plus index options, on pledged margin, through a broker API you authorise. Every order, stop and exit is placed in your account; you can see and stop all of it.
Algo trading involves risk. Backtested and past results do not guarantee future returns. Fintrens is not a SEBI-registered investment adviser.
Built so you can check every claim.
Firefly holds an API key that can place and cancel orders. It cannot withdraw, cannot see your login, and stops the moment you revoke it.
Your long-term holdings stay pledged as collateral, so the strategies run without fresh capital.
Every strategy family’s full history — entries, exits, stop hits, hit rate and maximum drawdown — labelled as simulated, before costs.
No strategy runs without a defined stop-loss and profit-take; Signals shows the median levels per stock.
When the book draws down past its limit, exposure is cut across the board until rules re-qualify.
A monthly bill only in months your account made money, net of costs. Losses are not billed.
From API key to first order.
Create an API key with trading permission only. Firefly never sees your password and cannot withdraw.
A short call fixes the capital allocated, the maximum drawdown you accept and which strategy families run.
Rules vote, capital moves to the ones working, orders go to your account with stops and exits attached.
Monthly statement with every trade; daily, the same verdicts are public on Signals so you can follow along.
What Firefly can and cannot do.
- Can place and cancel orders, read positions and margin.
- Cannot withdraw funds, change bank details, or see your login.
- Stops the moment you revoke the key at your broker.
- Reports every order in your broker’s own statements, not just ours.

Asked before signing up.
Getting started
What do I need to start?
An active trading and demat account with a supported broker, API access enabled on it, completed KYC, and capital of around ₹10 lakh so the strategies can diversify. Our onboarding toolkit walks through each step.
Do I have to open a new broker account?
No. Firefly works with the account you have if the broker offers an API. If you are opening one, Angel One has the smoothest API onboarding and we can refer you.
How long does setup take?
Usually one working day: API key, a short call to confirm capital and risk settings, then Firefly starts on the next session.
Money and risk
Can Firefly withdraw money?
No. The API key can place and cancel orders only. Withdrawals go from your broker to your registered bank account, by you.
Will I face losses?
Yes, some trades and some months lose. Every rule has a stop; the portfolio has a drawdown limit; the published backtests show the losing periods, not only the winning ones.
How is Firefly billed?
Monthly, and only when the account made a net profit that month. There is no lock-in; pause or stop at any time.
Control
Can I place my own trades on the same account?
You can, but we advise against it: manual positions compete with the strategies for margin and can trigger risk limits. Use a separate account for discretionary trading.
How do I stop it?
Revoke the API key at your broker, or tell us. Open positions are closed per rule or on your instruction.
