messageSubscribeeToro WebSocket APIWebSocketControl channel

Starts delivery of one topic or several: instrument:{instrumentId} for live rates, candle:{instrumentId} for candles, or private for the logged in user's order updates. An acknowledgement follows, then the pushes.

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.

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

The AsyncAPI document adds that a single binary frame is sent from time to time as a heartbeat.
