createSpreadOrder

Destructive

Open a new Bybit spread position by placing a limit or market order on a combination symbol. Use orderLinkId for tracking, set timeInForce for execution control, and confirm=true to submit.

Instructions

Create a new spread trading order.

Usage Scenarios:

  • Open a new spread position by placing a limit or market order on a spread combination symbol.

  • Use orderLinkId to assign a custom identifier for tracking purposes.

  • Use timeInForce to control execution behavior (e.g., PostOnly for maker-only fills).

Important:

  • The response is an acknowledgement only. The order may still be rejected asynchronously. Monitor the WebSocket stream for final order status.

  • A maximum of 50 open orders is permitted per account.

  • For limit orders, the price parameter is required.

Agent hint: POST endpoint requiring authentication. The symbol must be a valid spread combination symbol (e.g., "SOLUSDT_SOL/USDT"). Price is required for Limit orders. The response is asynchronous; subscribe to the WebSocket for definitive status updates. Max 50 open orders per account.

TDQS

A4.5/5.0
Behavior5/5

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

The description adds significant behavioral context beyond the annotations: the response is only an acknowledgement, final status must be monitored via WebSocket, there is a 50 open-order limit, and authentication is required. This helps the agent set correct expectations for an asynchronous, destructive trading operation.

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

Conciseness4/5

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

The description is well structured with usage scenarios and important notes, and the key information is front-loaded. Some redundancy exists between the 'Important' section and the 'Agent hint' section, repeating async behavior, price requirements, and the 50-order limit.

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 8-parameter order creation tool with no output schema, the description covers the essential operational context: asynchronous acknowledgement, authentication, limits, and key parameter usage. Minor gaps remain around qty semantics and explicit confirmation behavior, though confirm is well described in the schema.

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?

With schema description coverage at only 13%, the description compensates well by explaining symbol, price, orderLinkId, timeInForce, and orderType semantics. It does not explicitly describe qty or side, though side is self-evident from its enum; qty remains somewhat underspecified.

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 action and resource: 'Create a new spread trading order.' It further clarifies the target as a spread combination symbol and distinguishes this from generic order creation siblings like createOrder by emphasizing the spread-specific context.

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

Usage Guidelines4/5

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

Usage scenarios are explicitly provided: opening a new spread position with limit or market orders, and using orderLinkId or timeInForce for specific behaviors. However, it does not explicitly tell the agent when not to use this tool or when to prefer a sibling such as createOrder or wsCreateOrder.

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