nulls in Gdax ticker

[franklin770]

"best_bid" is null, NullValueHandling = NullValueHandling.Ignore,

Exception thrown: 'System.DivideByZeroException' in mscorlib.dll Ticker-{"type":"ticker","product_id":"BCH-BTC","price":0,"open_24h":0,"volume_24h":0,"low_24h":0,"high_24h":0,"volume_30d":"289.89382751","best_bid":null,"best_ask":"10.98"} Subscriptions-{"type":"subscriptions","channels":[{"name":"user","product_ids":["BTC-USD","BTC-EUR","BTC-GBP","ETH-USD","ETH-EUR","ETH-BTC","LTC-USD","LTC-EUR","LTC-BTC","BCH-USD","BCH-EUR","BCH-BTC"]},{"name":"ticker","product_ids":["BTC-USD","BTC-EUR","BTC-GBP","ETH-USD","ETH-EUR","ETH-BTC","LTC-USD","LTC-EUR","LTC-BTC","BCH-USD","BCH-EUR","BCH-BTC"]}]}

hi @franklin770. can you please provide the parameters you used for the websocket feed to get this error? looks like maybe the user and ticker channel?

[franklin770]

Hi Doug

It is on the ticker channel. there is definitely an exception being thrown

You have NullValueHandling.Ignore set, so it is being ignored

if you add Error = HandleDeserializationError you will catch it.

private static JsonSerializerSettings SerializerSettings { get; } = new JsonSerializerSettings { FloatParseHandling = FloatParseHandling.Decimal, NullValueHandling = NullValueHandling.Ignore, ContractResolver = new DefaultContractResolver { NamingStrategy = new SnakeCaseNamingStrategy() }, Error = HandleDeserializationError };

public static void HandleDeserializationError(object sender, ErrorEventArgs errorArgs) { // errorArgs.ErrorContext.Handled = true; //}

    }

However, looking into it more, there may be another error on my side. investigating.

BTW

I am getting this quite often.

    private void WebSocket_Error(object sender,

SuperSocket.ClientEngine.ErrorEventArgs e) { throw new GDAXSharpWebSocketException($"WebSocket Feed Error: {e.Exception.Message}") { WebSocket = WebSocketFeed, StatusCode = WebSocketFeed.State, ErrorEvent = e

        };
    }

Thanks

can't seem to replicate this and see any errors :/. the error i see being thrown in the exception above is DivideByZeroException. are you doing math around the data?

[franklin770]

Hi Doug.

I am doing math and the DivideByZeroException that I was getting is also on my side. I mistakenly thought that the DivideByZeroException that is being thrown in the websocket was the cause

Thanks for replying

Regards

glad its fixed 😄 will close this.

[franklin770]

Thx.

That's the problem with using the stupid sandbox. The prices are all off from the actual production prices, and it returns 0 for bid/ask etc.

I have to move to the realtime but my code is not there yet
