03 · How it works

Three steps to
your first paper trade.

No installs, no broker switch, no real money. Five minutes from credentials to a running paper strategy.

01

Connect Angel One

Save your SmartAPI key, client ID, MPIN and TOTP secret in Settings. Stored only in your browser.

02

Compose a strategy

Drag legs into the visual builder, set strike modes, define entry rules, SL and targets per leg.

03

Run on live quotes

Hit Run — OptionFlow opens, monitors, and exits positions on real tick data. Paper-only, always.

05 · Security

Your credentials
never leave your device.

  • Saved in browser local storage. No server, no database, no leak surface.
  • SmartAPI used only for quotes — order endpoints are never called.
  • Every fill is simulated. Your real broker balance is untouched.
