Data such as order book, ticker, last transactions are not sent directly after connection or user login is made. There is a specific channel and event for each process. By subscribing to these channels and events, this data is received. Once subscribed to a channel, the server sends events to that channel continuously to the client, unless the unsubscribe message is sent.
On the server, the channels generally represent the places where the transaction takes place (order book,last transactions, etc.) and the events represent the pair value (such as BTCTRY, ETHTRY, XLMUSDT) where the transaction takes place. In some special cases, these values may change. For example, to receive ticker data for all pairs, it is necessary to subscribe to the all event of the ticker channel . The server runs on 3 channels:
1) orderbook : Sends the transactions in the order book. The event name is the upper-case name of the pair. Ex: BTCTRY
2) trade : Sends data for recent transactions. Depending on the data type, incoming data can be individual or aggregated. The event name is the upper-case name of the pair. Ex: BTCTRY
3) ticker : Sends the current ticker data. There are two types of events. In the all event, the data for all pairs comes. To receive only events of a particular pair, you must subscribe to the upper-case pair name event. Ex: BTCTRY
