UAT/Sandbox Environment for Strategy Testing with Live Data

[jtutanota]

I wanted to inquire whether Upstox provides a UAT (User Acceptance Testing) environment or a Sandbox for testing trading strategies with live real-time market data in a virtual setting.

If such an environment is available, could you kindly share details on:

1. Access requirements or eligibility criteria.
2. Features supported (e.g., historical data, order simulation, latency).
3. Any limitations or costs involved.

Yes, Upstox does provide a sandbox environment for developers to test their trading strategies and API integrations safely. Sandbox | Upstox Developer API

• The sandbox mimics the live API closely, allowing full order flow testing (Place, Modify, Cancel).

• It’s free to use and doesn’t have live market time restrictions.

• You can simulate trades end-to-end without risking real money.

However, a few things to keep in mind:

• Only certain endpoints currently support sandbox mode (e.g., Place Order V3, Modify Order, etc.).
  • Place Order
  • Place Order V3
  • Place Multi Order
  • Modify Order
  • Modify Order V3
  • Cancel Order
  • Cancel Order V3

Running a complete trading application using sandbox alone can be tricky : once you initialize the Upstox client or configuration with sandbox=True, the entire instance behaves in sandbox mode for that session. Even if you later switch flags or change tokens, some internal settings (like host or order_host) may still point to the sandbox environment unless explicitly reset. This can lead to unexpected behavior, especially if you’re toggling between live and sandbox dynamically.

I have designed my app with such workarounds which I use to test my application completely on LIVE market and in SANDBOX Mode.
