Upstox
Upstox copy trading for your own accounts
Run your lead book on Upstox and mirror fills to every other desk on the floor — including brokers that are not Upstox.
Upstox connects with OAuth v2. You save the API key and secret, then complete login so CopyTrading can exchange the code for an access token.
Upstox access tokens expire each session. Use Re-connect at the start of the day so the master order book keeps polling. Watchlist LTP from an Upstox master is live when the token is valid.
Children can be Upstox, Dhan, Zerodha, Angel One, or any other wired broker. Same contract, per-child size, optional shadow.
How you connect
Register the exact Upstox redirect URI (no trailing slash) on the developer app, then connect from the watch desk.
