Launch of Kill Switch API​

Effective April 10, 2026

We are introducing the Kill Switch API — a risk management feature that gives traders programmatic control to enable or disable specific trading segments. Built on top of the kill switch concept, these APIs help prevent impulsive or emotionally-driven trading decisions by letting users temporarily halt activity in one or more segments.

What's New?​

  1. Kill Switch API

    • Description: Enables or disables one or more trading segments in a single request. When a segment is disabled, all open orders in that segment are cancelled and new orders are blocked.
    • Documentation: Kill Switch

  2. Kill Switch Status API

    • Description: Retrieves the current kill switch status for all trading segments, indicating whether each segment is active and whether the kill switch is engaged.
    • Documentation: Kill Switch Status

Key Behaviours​

  • All open positions in a segment must be closed before the segment can be disabled.
  • All open orders in the segment are cancelled automatically when it is disabled.
  • A 12-hour cooling period applies after disabling a segment — it cannot be re-enabled until the cooling period expires.
  • If any segment in the request fails to update, none of the other segments in the same request will be updated.

How to Get Started​

Refer to the documentation links above for detailed usage instructions, request parameters, and code examples. The APIs are available at the standard Upstox API endpoint https://api.upstox.com/v2/user/kill-switch.
