Connectivity problems

[NinjaTrader_JoshP]

adamus,

Can you please provide exact dates in use? It will probably just be easier if you took a screenshot of your Data Series window and sent that in so we can use exact settings you are to test. Thank you.

[adamus]

Josh, there are no settings in that menu I can change that will get around this problem. However since you requested it, I have included a screenshot.

Hello adamus,

I tested the exact same settings in the Data Series menu, however I could not reproduce the IB error message.

I created a new chart and setup all settings as per your screenshot. I did not have any chart template selected. I am not sure if you have a chart temlpate loaded in the chart - unfortunately I cannot tell this from your screenshot.

If you do make use of a chart template, could you please post so we can test it.

Hi Jason,

I don't use a chart template and just to make sure, I deleted the only one I'd ever saved.

I know you have to go through all these steps but it's not going to help because when it happens, it happens anywhere. I won't be able to download historical data and I will see that message in the IB log.

The next thing you should try is setting up a strategy with barsRequired and DaysToLoad set to cause the strategy to load a couple of days of data. That won't work either.

I am wracking my brains to think of a reason why it should work for you and not for me.

It is particularly bad late PM before NY close.

You are on Windows XP SP2 or Windows 7 64-bit?

You are using TWS 906.8 or 906.9? I use 906.8 on XP and 906.9 on Win7.

You have a firewall blocking everything except the usual HTTP, HTTPS, SMTP, POP, IB, Skype etc? What port would NT use to communicate other than HTTP & SMTP?

Hello adamus,

I tested it on Windows Vista and Windows 7 32-bit. I have TWS version 906.8 installed.
I have security software installed on my machines, which does not block NinjaTrader.

NinjaTrader connects through port 7496 in order to connect to IB - you can find it in the IB connection wizard in NinjaTrader.

NinjaTrader connects through one of the two IP addresses and ports below to connect to its license server.

IP address: 74.200.197.238 and 64.38.21.160

Port: 80 and 443

Could you please send us the automated strategy that caused the error message as well. If you do not like to post it on our forum, please send it to support[at]ninjatrader[dot]com. Put 'Attn Jason' in the subject header and reference this forum thread.

Poeds, you have got to be kidding me! You got the "Invalid time period" message with IB?

How did you work out that it was IPv6 causing the problem?

When you say you disabled IPv6 on the LAN, where did you disable it? On your whole LAN or just your trading workstation IP config?

OK then it can't be anything to do with ports or firewalls. I'm running IB and NT on one machine together, and I'm running NT on its own on WinXP with IB running on a third machine. They both exhibit the same problems.

As for strategies, I get the problem even if I'm trying to run the SampleMACrossover and I've had it with every other strategy I've ever enabled.

What do you think about the IPv6 message from poeds? How would I disable IPv6?

Thanks

[NinjaTrader_Jason]

I assume Poeds refers to Zen-Fire with 'zf'.

I am not sure how you can disable IPv6. I searched for it in Google and it listed the results at the link below.

The latest info I got from Interactive Brokers was this:

Initial Description: HMDS data farm connection continually breaking

Hello There,

Unfortunately, we cannot ignore the warning message. This is hard-coded on our server side. It is a standard protocol if the request is invalid, then the designated server will throw some error messages.

Of course this doesn't explain why sometimes it works, sometimes it doesn't. Personally I think it has more to do with the time of day.

However it is obvious that IB are refusing to take the issue on because they see the error caused by NT as the primary roadblock.

I'd be happy to do anything more that will help - this is for me the most important and high impact problem with NT.

[NinjaTrader_Jason]

Please let us know when you have a reproducible scenario that consistently causes the error message. Unfortunately we cannot do much without one.

[adamus]

Jason,
it's reproducible everyday. It has been making my life miserable since I started running strategies.

What haven't I told you already that you need to know?

[NinjaTrader_Jason]

Unfortunately, we cannot reproduce it on our end when we perform the steps you provided so far. This would be required in order to further investigate why such steps result in the error that IB/TWS throws.
