messageMarketDataCloseSubscriptionRequestDXtrade Push APIWebSocketMarket data

Closes a market data subscription, by the requestId of the request that opened it. The server confirms, and no more market data is sent for that subscription.

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

Independent and unofficialdemo.dx.tradechecked

This is a message of the DXtrade Push API, not an HTTP endpoint. It has no method and no path: it is sent as JSON or XML over an open WebSocket connection.

Besides the common errors, the section lists error code 2, Entity not found, where the subscription does not exist or is already closed.
