KrakenOrderbookOptions error messages

Code (this is basicly from the examples): KrakenSymbolOrderBook orderBook = new KrakenSymbolOrderBook("XXBTZEUR", 1, new KrakenOrderBookOptions(20));

Gives an error message: CS1503 Argument 1: cannot convert from ‘int’ to ‘Kraken.Net.Interfaces.IKrakenSocketClient’

When i change it like this:

var client = new KrakenSocketClient(options);
KrakenSymbolOrderBook orderBook = new KrakenSymbolOrderBook("XXBTZEUR", 1, new KrakenOrderBookOptions(client));

The error is gone But now when connecting using the following:

 var startResult = await orderBook.StartAsync();

            if (!startResult.Success)
            {
                Console.WriteLine("Error starting order book synchronization: " + startResult.Error);
               return;
            }

It stops, because startResult.Error is: {3: Server error: Subscription depth not supported}

Which makes sense because a client is not a depth 😃 Is this an issue, or a user error ?

The websocket connection works based on events. So when you’re calling SubscribeToTickerUpdates you connect to a stream and when data is received on that stream you get an update. To handle the update you’ll have to pass an update handler to the subscribe method. This is what the data => {} bit is. Between the {} you’ll have to handle the data. What to do with it is obviously up to you, but having a console application this will simply write the price of the latest tick to the console:

client.SubscribeToTickerUpdates("XBT/EUR", data => { 
      Console.WriteLine(data.Market + " last trade price: " + data.Data.LastTrade.Price);
});

Yup that’s fine. (You could shorthand it by writing client.SubscribeToTickerUpdates("XBT/EUR", Ticker);, which is the same)
