  "canceled_orders": ["SB-250408001042620"],
  "failed_cancellations": [
    {
      "orderid": "SB-250408001043015",
      "message": "Failed to cancel"
    }
  ],
  "mode": "analyze"
}

Request Body

Parameter	Description	Mandatory/Optional	Default Value
apikey	Your OpenAlgo API key	Mandatory	-
strategy	Strategy identifier	Mandatory	-

CancelAllOrderSchema declares exactly these two fields and both are required. Omitting strategy returns HTTP 400, and any additional field returns HTTP 400 as well.

Response Fields

Field	Type	Description
status	string	"success" or "error"
message	string	Summary of cancellation results
canceled_orders	array of strings	Successfully cancelled order IDs
failed_cancellations	array	Orders that failed to cancel. See the note below on its element type
mode	string	"analyze" in analyzer mode; absent in live mode

Failed Cancellations Element Type

The element type differs by execution path, so handle both:

Path	Element
Live broker	A plain order-ID string
Analyzer/sandbox	An object with orderid and message

There is no reason key on either shape. The live broker mappers only record which order IDs failed; they do not surface a per-order failure reason.

Notes

• Cancels all open orders including:

  • Open limit orders

  • Pending trigger orders (SL, SL-M)

  • AMO orders (if supported by broker)

• Orders that are already executed or in transit cannot be cancelled

• The API returns success even if some orders fail to cancel

• The strategy value is used for event logging and tracking; it does not filter which orders are cancelled. Every eligible open order is cancelled regardless of which strategy placed it.

• This is a bulk operation - use with caution in production

• Rate limit: API_RATE_LIMIT, not ORDER_RATE_LIMIT

Use Cases

• Emergency exit: Cancel all pending orders when market moves unexpectedly

• End of day cleanup: Cancel unfilled orders before market close

• Strategy reset: Clear all pending orders before starting fresh
