batchAmendOrders

Destructive

Amend multiple existing open orders in a single call across spot, futures, or options. Use orderId or orderLinkId to adjust price, quantity, or triggers on unfilled orders.

Instructions

Modify multiple existing open orders in a single API call.

  • Max 20 orders per request for futures/options, 10 for spot

  • Each order requires either orderId or orderLinkId

  • Only unfilled or partially filled orders can be amended

  • Check retExtInfo.list[].code for per-order status

  • Response is acknowledgment only; confirm via WebSocket order stream

Agent hint: Use this endpoint to modify multiple orders at once. For a single order, use amendOrder instead. TradFi: use category=spot for xStock batch amends, category=linear for equity/commodity perpetuals.

TDQS

A4.8/5.0
Behavior5/5

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

Annotations already mark this as destructive and non-read-only, and the description adds valuable behavioral detail beyond that: the response is acknowledgment-only, per-order status is in retExtInfo.list[].code, and final confirmation must come via the WebSocket order stream. This tells the agent what to expect and what to check.

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 well-structured with purposeful bullet points, a clear agent hint, and a domain-specific TradFi note. Every sentence adds actionable information, and the main purpose is front-loaded.

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

Completeness4/5

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

For a complex mutation tool with no output schema, the description covers the critical call requirements, acknowledgment semantics, and per-order status checking. It stops short of fully explaining every nested request parameter and error-handling behavior, but the essential context for invoking the API correctly is present.

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?

Schema description coverage is only 33%, so the description must compensate. It does explain the key request semantics: each order needs orderId or orderLinkId, the per-request limits differ by category, and category=spot/linear maps to TradFi use cases. However, many optional nested fields like triggerPrice, tpslMode, and takeProfit are left without any description, so semantic coverage is still incomplete.

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 description opens with a specific verb and resource: 'Modify multiple existing open orders in a single API call.' It also explicitly names the single-order alternative 'amendOrder', so the tool is clearly distinguished from its most similar sibling.

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?

Usage guidance is explicit: 'Use this endpoint to modify multiple orders at once. For a single order, use amendOrder instead.' It also provides concrete eligibility constraints, such as max order counts, the orderId/orderLinkId requirement, and that only unfilled or partially filled orders can be amended.

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