Is there a way to simulate a data provider connection loss?

[9817_dynamic]

Hello,

Is there a way to simulate a data provider connection loss without manually disconnecting my internet connection?

Is there code that I can temporarily add that forces a data connection loss without terminating the strategy?
I have the strategy's ConnectionLossHandling set to KeepRunning.

I am trying to simulate a message being sent by a strategy when the ConnectionStatus.ConnectionLost state occurs.

If I disconnect my internet, NT8 cannot resolve the SMTP host and server to send the message.

I am getting the "error sending a mail message" message, so I think it is working, but I would like to test it.


Thank you for any info.

Hello 9817_dynamic,

Thank you for your post.

You could use a program such as Microsoft's TCPView that lets you sever specific connections to simulate this. This is publicly available here:

https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview

You'd want to look for NInjaTrader in the list, right click on a NinjaTrader Connection and click on Close Connection to test - there's usually a couple, so it may take a bit of trial and error to get the correct one.

Please let us know if we may be of further assistance to you.

I didn't even think of a third-party solution. I was looking for something inside NT8.

Thank you very much for the info and suggestion!

Your suggestion to use TCPView worked very well, NinjaTrader_Kate. Thank you again!

I'm testing this on a vps, so I can't simulate the disconnect manually.

I tried to close the connections with this software but those auto-update quickly. I was able to cut the connection with the firewall (candles stop loading by cutting the connection to Ninjatrader.exe), but Ninjatrader doesn't take it as a disconnection, nothing happens in the log. Should I cut the connection to a particular port ? Is there any other way to do it? Thank you

Hello rocker84,

Thank you for your reply.

Unfortunately I'm not aware of another way to simulate a connection loss. There may be third party applications that could do this but I'm not aware of any particular one.
