Socket

08:22:36:288 | Error | Couldn't open socket stream: Method not found: 'System.Threading.Tasks.Task`1 WebSocket4Net.WebSocket.OpenAsync()'. 08:22:36:370 | Info | Disposing socket client, closing sockets

been working fine untill the update, wierd.

Hi, Method not found sounds like there is a mismatch in versions somewhere. Try clear the packages folder and caches to make sure the latest versions get retrieved.

[JKorf]

Hm, never mind that, seems to be an issue when not using .net core, some limitations in a reference library. Working on a fix.

[JKorf]

Can you try version 3.0.6? Should be fixed in that one

[snrchang]

yeah that sorted it, But for some reason it just closes socket.

02:28:41:162 | Info | Started symbol ticker stream for nanobtc 02:28:41:280 | Info | Disposing socket client, closing sockets

Using client = New BinanceSocketClient() Dim successDepth = client.SubscribeToSymbolTicker("NANOBTC", Sub(data)

                     BncWriteLog(data.BestAskPrice.ToString)
                     socketTick += 1
                 End Sub)
                client.UnsubscribeFromStream(successDepth.Data)
                BncWriteLog("Lost Using....")
            End Using

There is no change it code from when it was previously working before update.

[JKorf]

This is intended, when the socket client gets disposed the connection closes. It should work when you don't use Using, but instead just create the client as a variable

[snrchang]

ok cool, weird it wasnt doing the before. Also setting the new Default options like this: `

 Public BncClient As New BinanceClient 
    Private Async Sub BncConnectBtn_Click(sender As Object, e As EventArgs) Handles BncConnectBtn.Click
        Dim defaultOptions As New BinanceClientOptions
        defaultOptions.AutoTimestamp = True
        defaultOptions.TradeRulesBehaviour = TradeRulesBehaviour.AutoComply
        defaultOptions.LogVerbosity = CryptoExchange.Net.Logging.LogVerbosity.Debug
        BncClient.SetDefaultOptions(defaultOptions) <-- Gets warning about "access of shared member will not be evaluated" 
end sub`

It seems also not setting the autotimestamp since i still get the error of sever time is 1000ms defferent. Thanks

[JKorf]

I´m not too familiar with VB.Net, but I think you´re using the static SetDefaultOptions function on an instance. I think what you want to be doing is BinanceClient.SetDefaultOptions(defaultOptions). Do this before you actually create your client and when you create a new client it should have the settings you set as default

[snrchang]

Ahh i see, so before the update i could set autotimestamp like this

dim Client As New BinanceClient
client.AutoTimestamp = True
client.TradeRulesBehaviour = TradeRulesBehaviour.AutoComply

Now these option are not there. Also how do you stay inside the using block for symbol ticker then decide to leave? also is there a socket event handle for symbol ticker, for example if loss of internet so i can reconnect the socket. Once again thanks for all of this.

[JKorf]

Easy reconnecting is something I still need to implement.

This will set the settings:

        Dim options As New BinanceClientOptions
        options.AutoTimestamp = True
        options.TradeRulesBehaviour = TradeRulesBehaviour.AutoComply
        options.LogVerbosity = CryptoExchange.Net.Logging.LogVerbosity.Debug
        BncClient As New BinanceClient(options)

You can provide the options in the constructor of the client.

Probably easiest to use the socket client is without Using, something like:

Dim client as BinanceSocketClient
Dim subscription as BinanceStreamSubscription

Function Start()
    client = New BinanceSocketClient()
    subscription = client.SubscribeToSymbolTicker("NANOBTC",
        Sub(data)
                 BncWriteLog(data.BestAskPrice.ToString)
                 socketTick += 1
             End Sub)
End Function

Function Stop()
    client.UnsubscribeFromStream(subscription.Data)
End Function    

Might be some syntax errors, I never use Vb.Net

[snrchang]

mate, thanks so much, I had coded it without using blocks. Didnt realise you can pass the options to the client in the constructor.

After half way coding cryptopia Libary i realise how much your wrappers are doing. Cryptopia is a nightmare. Thanks Jkorf

[JKorf]

It can be quite a hassle ;) You're welcome mate!
