See [Releasing Capital on Disconnect](/latest/websocket-session#releasing-capital-on-disconnect) for when to use which. ## OpenAPI ````yaml POST /v1/matching/orders/cancel-all openapi: 3.1.0 info: title: Options Matching API version: 1.0.0 description: >- Order management endpoints for Rails Options.
