Setting up the widget

1. Get a key

Sign in and open your keys, then click Create key. The key is shown once, at that moment. Copy it before leaving the page — only a hash is stored on our side, so it cannot be shown again. Lost keys are deleted and replaced, not recovered.

2. Put it in the widget

Right-click the widget window and choose Settings, paste the key into the API key field, and click OK. The widget reconnects immediately — no restart needed.

You can also edit config.json next to the executable by hand:

{
    "zmq": {
        "api_key": "nw_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        "personal_symbols": []
    }
}

3. Add your contracts

Right-click the widget and choose Add Token. Enter the full trading symbol, for example NIFTY07APR2622250PE. You can track two contracts alongside NIFTY 50. Contracts are dropped automatically once they expire.

Keeping keys safe

• A key identifies your account. Treat it like a password.
• Use a separate key per machine, so you can revoke one without disturbing the others.
• Check Last used on your dashboard. If a key was used from somewhere you do not recognise, delete it.
• Deleting a key takes effect within a minute, everywhere it is in use.

Troubleshooting

“Invalid key” in the widget means the key was deleted, mistyped, or belongs to an account that has not confirmed its email. Create a fresh key and paste it again.

“Disconnected — retrying” means the key is fine but the server is unreachable. The widget keeps retrying on its own and reconnects when the server returns.
