I am listing to instrument updates in WebSocket channel.
The endpoint is the same one on the test code provided. As explained in the documents, first I got the Refresh message. After that I got Update messages which is also the expected behavior.
When I go through the times that update messages are received, I noticed that it is always for 10 min interval. Is it because this is test system ? (Because from the document I understood that the update message will be sent on an activity in the market).
