Sometimes I don't automatically connect to a provider when Ninja starts up.

But I still have workspaces that open charts with indicators.

In this case I would like to bypass some code in OnStartup. (when there is no connection, or ninja starts with no connection)

Any ideas?

this is for NT7

See the OnConnectionStatus() method.
You can switch your code on/off accordingly.

OK, it looks like it should work, but I get this compile message... (it is in a working indicator that otherwise compiles normally)

'NinjaTrader.Indicator.AANews.OnConnectionStatus(NinjaTrader.Cbi.ConnectionStatus, NinjaTrader.Cbi.ConnectionStatus)': no suitable method found to override

===============================================================================

bool connected = false;


#region OnConnectionStatus
protected override void OnConnectionStatus(ConnectionStatus orderStatus, ConnectionStatus priceStatus)
{
if (priceStatus = ConnectionStatus.Connected)
connected = true;
else
connected = false;
}
#endregion

===========================================================================

not finding much on the web for this error

See OnConnectionStatus no suitable method found to override - NinjaTrader Support Forum .

P.S.: It boils down to the fact that you have to trigger your indicators from a strategy.

Ok, then that method won't work for me because these are chart indicators not used in any strategy....

any other ideas?

this is not instantiated in OnStartUp when there is no connection....

Bars.MarketData.Connection.Options.Provider

if I check it for null, it tells me it is a non-nullable field....

how can I tell if it is instantiated (I'm not a C# guru...)

If it is not instantiated then I know there is no connection and I can bypass the code I want...

Thanks!

OK, it can be compared to null....

but it is not instantiated so I get a run error "Object reference not set to an instance of an object" when comparing (==) to null

ideas?

In an indicator you have to attach your own callback in OnStartup to get access to the same functionality:

 

Code

NinjaTrader.Cbi.Globals.Connections.ConnectionStatus += new ConnectionStatusEventHandler(OnConnection);

Check the 'private void OnConnection' code in the 'Accounts and Executions' section of ChartMinder if needed, but a cut down example is:

 

Code

private void OnConnection (object sender, ConnectionStatusEventArgs e) { if (e.Status == ConnectionStatus.Connecting) { } else if (e.Status == ConnectionStatus.Connected) { } else if (e.Status == ConnectionStatus.ConnectionLost || e.Status == ConnectionStatus.Disconnected) { } }

You also need to disconnect the handler in OnTermination:

 

Code

NinjaTrader.Cbi.Globals.Connections.ConnectionStatus -= new ConnectionStatusEventHandler(OnConnection);
