Connect with your own keyGroww kill switch and daily loss limits, without handing over your account
Groww gives you a stop-loss on a trade. It does not give you a stop-loss on your day. LossGuardian sits alongside your Groww account, watches your realised and unrealised P&L in real time, and alerts you the moment you hit the limit you set, before the day turns into the one you regret.
Read-only. LossGuardian cannot place, modify or cancel an order in your Groww account. It warns you, and you act. You log in on Groww’s own screen, and we never see or store your password.

A short walkthrough of connecting Groww, then the same steps in writing below.

Trade as normal. LossGuardian watches in the background and speaks up only when you cross a line you drew.
The missing guardrail in Groww
Most risk-management tools do not support Groww at all, so Groww traders are told to change broker to get discipline software. That is backwards. And once a tool does hold your trading history, the question becomes who else can read it, and what happens when you change machines.
Daily loss limit
A rupee limit and a percentage of capital, running together. Cross either and the session is stopped.
Revenge trading caught by timing
Re-entering too soon after an exit is what gets flagged, so it is caught even when the trade happens to win.
Consecutive loss cooldown
Hit your streak limit and a countdown holds before the app treats you as clear to re-enter.
Alerts you cannot dismiss
An always-on-top stop, not a toast you can click away while tilted.
What Groww traders get most out of
Two accounts never merge
Every file (trades, alerts, hard-stop state, analytics, backups) is namespaced by broker plus a hashed account id. Run two accounts on the same broker and their histories stay separate, permanently.
Encrypted, versioned local backups
Backups are sealed with scrypt-derived keys and AES-GCM before anything is written, fired automatically at day-close and session-end. Change machines without losing your history, and without that history being readable by anyone else.
Export your session, journal it properly
A full day of trades, discipline stats, alerts and equity curve exports as structured markdown, for the current session or any past day, ready to paste into an AI assistant or a Notion journalling workflow.
Is this a Groww kill switch?
Not in the sense of software that reaches into your Groww account and closes your positions for you. LossGuardian is read-only: it cannot place, modify or cancel an order. What it does is enforce the rule behind a kill switch: the moment your loss limit, trade count or losing streak is breached, an always-on-top alert you cannot click away tells you to stop for the day, and a cooldown holds before it treats you as clear to re-enter. You close the trade, in Groww. That is the part that builds the habit, and it is the part software cannot do for you.
Groww has its own kill switch, which it calls Lock F&O Trading. LossGuardian cannot switch it on for you, and never will. What it does is open Groww’s own page for it from the hard-stop popup and from Risk Manager settings, so finding it takes one click instead of five. You switch it on yourself, in Groww. Check Groww’s own help pages for how long it lasts, because that differs by broker and can change.
One price. Every broker.
Using LossGuardian with Groww costs exactly what it costs with Zerodha, Fyers, Dhan, Upstox or Angel One. Other tools charge you more for using a bigger broker. We don’t.
