Submit multiple trade orders in a single request. Each order is executed sequentially using the same logic as the single Trade endpoint.

Overview

Use this endpoint when you need to place multiple orders at once — for example, entering positions across several markets in a single skill cycle or placing hedged entries on both sides of a market. Each order in the batch is processed independently. If one order fails, the remaining orders still execute. The response includes individual results for every order.

Maximum 20 orders per batch request. Each order undergoes the same validation and risk checks as the single trade endpoint.

Response Fields

Field	Type	Description
`total`	integer	Total number of orders submitted
`succeeded`	integer	Number of successfully executed orders
`failed`	integer	Number of failed orders
`results`	array	Array of individual trade results (same schema as Trade response)

Common Errors

Code	Meaning
`400`	Invalid request body, empty orders array, or exceeds max
`401`	Missing or invalid API key
`500`	Server-side error

Notes

Orders are executed sequentially, not in parallel. Each order completes before the next begins.
Each order undergoes independent risk checks and Polymarket API submission.
A failed order does not stop subsequent orders from executing.
The orders field in each result matches the single trade response schema exactly.
