Cancellation stops further child-order scheduling. An already-submitted child order may still fill while cancellation completes, and those fills are kept. The strategy normally finishes as `cancelled` with `reason: userRequested`; if the in-flight order completes the requested volume, it can finish as `closed`. Poll `QueryStrategies` for the terminal status and final execution totals. Terminal strategies are returned by `GetClosedStrategies`. **API Key Permissions Required:** `Orders and trades - Cancel & close orders` ## OpenAPI ````yaml /openapi/spot-rest.yaml post /private/CancelStrategy openapi: 3.0.0 info: title: REST API version: 1.1.0 description: '' servers: - url: https://api.kraken.com/0 description: Production Server security: - API-Key: [] API-Sign: [] tags: - name: Market Data - name: Account Data - name: Trading - name: Algo Trading description: > Algo Trading endpoints create and manage **strategies**: parent instructions that Kraken executes on your behalf as a series of regular child orders. The only strategy available today is **TWAP** (time-weighted average price). A TWAP buys or sells a total `volume` evenly between `starttm` and `expiretm`. How child orders are sized, timed and placed is managed by Kraken and may change as execution improves. An algo runs as a strategy. In Kraken Pro, TWAP strategies show under Bots. ### Strategy lifecycle `pending` → `open` → `closed` | `expired` | `cancelled` - `pending`: accepted, waiting for `starttm`. - `open`: running, child orders are being placed. - `closed`: the full `volume` was filled before `expiretm`. - `expired`: `expiretm` was reached before the full `volume` was filled. - `cancelled`: cancelled with `CancelStrategy`. TWAP child orders are immediate-or-cancel limit orders and do not rest on the book. Completed child orders appear in `ClosedOrders`, and fills appear in trade history. Use the strategy endpoints to monitor overall progress. - name: funding-beta x-group: Funding (Beta) x-displayName: Funding (Beta) - name: Funding x-group: Funding (Legacy) x-displayName: Funding (Legacy) - name: Subaccounts description: >- Subaccounts are currently only available to institutional clients. Please contact your Account Manager for more details. - name: Earn description: > The earn API allows interacting with all of Kraken's yield generating products. It replaces the old `/staking` part of the API. The different available earn products are represented by earn strategies. This corresponds to the legacy `Staking/Assets`. `Stake`/`Unstake` are replaced by `Allocate`/`Deallocate`. ### Overview of the available endpoints under `/Earn`: - `Strategies` - list all earn strategies for which you are eligible or have a balance. - `Allocations` - lists the balance in your earn account for each strategy. Requires the `Query Funds` API key permission. - `Allocate`/`Deallocate` - allocate/deallocate to an earn strategy through an async operation. Requires the `Earn Funds` API key permission. - `AllocateStatus`/`DeallocateStatus` - verifies the state of the last allocation/deallocation. Requires the `Earn Funds` or `Query Funds` API key permission. ### Example usage: ### Determine which funds are earning rewards: 1. Call `Strategies` to obtain information about the relevant strategy. The `lock_type` field shows whether bonding/unbonding funds are earning yield. The relevant fields are `bonding_rewards`/`unbonding_rewards`. 2. Call `Allocations` for the relevant strategy. From the previous step, for strategies where bonding/unbonding does not earn yield, substract these balances from `amount_allocated.total` to determine which balances are currently earning. ### Get allocatable balance: Call `/0/private/BalanceEx`, subtract `hold_trading` amount. Remaining balance is available for allocation to a strategy. ### Geo restrictions: Some earn strategies are not available in all geographic regions. `Strategies` will return only strategies available to the caller. - name: Transparency paths: /private/CancelStrategy: post: tags: - Algo Trading summary: Cancel Strategy description: > Cancel a `pending` or `open` strategy by `strategy_id`.
