Websocket

You can connect to Avanza Websocket API using the client. The client will handle connection/pinging.

You can set up a new connection like this:

_, err := client.Auth.Authenticate(context.Background(), username, password, totpSecret)
if err != nil {
    log.Fatalf(err.Error())
}

timeout, _ := context.WithTimeout(context.Background(), 90*time.Second)
_, quotes, err := client.Websocket.StreamQuotes(timeout, "19000") // 19000 = USD/SEK
if err != nil {
    log.Fatalf(err.Error())
}
for q := range quotes {
    log.Println(q)
}

Websocket stream methods will return a channel containing all messages that will come in. If the context is closed we will close the channel and continue your program.

Subscription strings

Here is a quick explanation how to build the subscription params string.

	Single	Multiple
Quotes	{orderbookId}	{orderbookId1},{orderbookId2}
OrderDepth	{orderbookId}	{orderbookId1},{orderbookId2}
BrokerTradeSummary	{orderbookId}	{orderbookId1},{orderbookId2}
Trades	{orderbookId}	{orderbookId},{orderbookId}
Positions	{accountID}	{accountID1},{accountID2}
Orders	{orderID}	{orderID1},{orderID2}
