stopStrategy

Destructive

Stop a running strategy and cancel all pending orders to react to market changes or unfavorable execution, preserving filled trades.

Instructions

Terminates an active strategy and cancels all associated pending orders.

When to use:

  • Stop strategy before it completes naturally

  • React to changing market conditions

  • Cancel strategy that has unfavorable execution

  • Emergency stop for risk management

What happens when you stop:

  1. Strategy status → Terminated

  2. All pending orders → Canceled immediately

  3. Partially filled orders → Cancel remaining unfilled portion

  4. Filled orders → No change (remain as filled)

  5. Strategy execution stats → Preserved for history

Important notes:

  • Stopped strategies cannot be restarted

  • To continue, create a new strategy with remaining size

  • Strategy terminateType will be set to "UserStop" (1)

  • All child orders are canceled, not just active ones

  • Rate limit: 10 requests per second per UID

Agent hint: Use this endpoint when user wants to stop a running strategy. Common requests: "stop my strategy", "cancel TWAP", "stop strategy X". Requires strategyId - if not provided, query strategy list first.

TDQS

A4.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description goes far beyond annotations, detailing exact outcomes: status becomes Terminated, pending orders canceled immediately, partially filled orders have remaining portion canceled, filled orders unchanged, stats preserved. It also discloses irreversibility, terminateType value, child-order scope, and a rate limit. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with a one-sentence summary, followed by well-structured sections for use cases, effects, notes, and agent guidance. While somewhat long, each bullet serves a purpose and the headers make scanning easy. The structure earns its length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutating tool with no output schema, the description covers the full lifecycle of a stop operation: when to call, expected side effects on strategy and orders, irreversibility, rate limiting, and how to obtain the required parameter. The only minor omission is a response format, but no output schema creates an expectation for one. Overall, it equips an agent with everything needed to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema covers confirm thoroughly but leaves strategyId undocumented; the description compensates by stating strategyId is required and telling the agent to query the strategy list first if it's missing. The description does not elaborate on confirm because the schema already does. This partial compensation raises the value above baseline but doesn't fully explain the expected format or source of strategyId.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first sentence states a specific verb (Terminates), the resource (active strategy), and a key side effect (cancels all associated pending orders). This clearly distinguishes stopStrategy from strategy-creation and query siblings. No ambiguity about what the tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

A dedicated 'When to use' section enumerates four concrete scenarios, and the agent hint provides common user phrasings like 'stop my strategy'. It also advises creating a new strategy to continue, an explicit alternative path after stopping. This gives an agent clear criteria for selecting this tool over sibling operations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
