Connectivity

[TraderEyal]

Hi, I'm having some connectivity issues. Data sometimes lags, sometimes freezes or slows down and on occasion I get NO PSSWOD and NO DM.
All this is while my interenet connection is up and running fine. IB's TWS works fine through all these mini outages and quotes are streaming in.

What could be the reason for this and how to eliminate or reduce this problem. It occurs a 2-3 times a day, 4 days out of 5.

Thanks,
Eyal

Eyal,

We haven't had any reports of poor connectivity this morning. The fact that this is occurring on such a regular basis generally indicates there may be something happening behind the scenes. I'm not sure if you have gone through the following article from our Knowledge Base. If not, this is a good place to start as it addresses some of the major sticking points from a connectivity perspective that can cause this sort of behavior with eSignal.

[TraderEyal]

Hi Duane, I just checked through the article. None of the issues listed seems to be a problem over here. Pinging and tracert produced reaonable results. Pings had 0% loss and tracert gave between 180 and 200ms. (I'm on 1.5 ADSL). I did get an occasional packet loss, for e.g. at 151.164.243.1 belonging to sbcglobal.net

These mini outages, although relatively frequent are quite short-lived, lasting just a few moments (under 10 seconds usually). The point is though that TWS is very sensitive to connectivity and when something happens on the network it is the first to pop up. It does not pop-up though when those eSignal outages occur.

I am assuming that I am connceted to a US based server? Is there an Asian server maybe I can test against?

Thanks for your help,
Eyal

Hi Duane, Any update on this issue?

From what I can see eSignal's Data Manager only uses TCP, is this correct?
I investigated the tracert results with my ISP and they only do ICMP limiting which is why we've got packets loss on tracert. Otherwise the whole route is functioning fine from my PC up to your network.

Regards,
Eyal

Hi Eyal,

Thank you for taking the time to run the trace routes. You are correct; the DM does use TCP for the transmission. I'm not sure when you ran the various trace routes, but I think that if the trace could be run during the time at which the DM goes to a NO PSSWOD state, we may see the cause of what is behind all of this.

I'm not sure if you used a DOS prompt to run the trace, but one application I have found particularly helpful is PingPlotter. The shareware version is very easy to use and quite telling when evaluating a connection. If you could run the trace when the DM goes into the NO PSSWOD state, I think we can work to resolve this for you. Thanks again for the details you've provided.

Still having problems

Hi Duane, I'm still experiencing connectivity issues. This time it's not only disconnects of DM but major lags (compared to IB). This is throughout the day and the tracert shows everything is fine.

The DM NO PASSWD problem btw was an ISP issue I believe as it happens when there are time outs at certain nodes.

Is there anything that can be done to check why this is happening and resolve this?

Thanks
Eyal

Hi TraderEyal,

I was looking through my Private Messages in hopes I had your username locally, no such luck. If possible, could you please Private Message me your eSignal username? I would like to take a look at the connections from this end in hopes we can find something telling. Please let me know.

[TraderEyal]

Just sent it.

Thanks

tracert

Here's a very recent tracert during an outage of DM I just had a couple of minutes ago:

TraderEyal,

Thanks for all the details. I did some checking on your account and a couple of things stuck out. One of the most evident issues is that it looks like your IP address is constantly switching. There are typically two causes for this; one, your account is attempting to log in at two different locations, or two, you have a dynamic IP address through your ISP and the address is being switched for whatever reason.

Regardless, at this point, if you could contact our Technical Support department when it is occurring, we can work to determine which of the two scenarios we are dealing with. Thanks.

Here is the contact information for our Technical Support Department

[TraderEyal]

Hi Duane,

I've contacted tech-support and they opened a ticket 2003814 although they are not sure there is anything they can do about this problem.

Btw, re-installing eSignal today helped to a certain degree with the lag (but not the disconnects). I wonder if this is temporary or if something was resolved there.

Thanks for your help.

Singnet's DSL broadband uses dynamic IPs. I suppose you need to define "constantly switching".

I have been experiencing periods of disconnection too. But it's not very often. Does happen once in a while for me. Tends to be in the early hours of the US day session most of the time.

[TraderEyal]

Hi Anson, thanks for the input. I am indeed on Singnet's ADSL.

The problem is not just disconnects but also quite a bad lag. I had Singtel come over and check the signal from within my apt as well as monitor the connection during market hours from their data centre and everything seems to be fine according to them.

Anyways, other than getting a dedicated direct leased line I don't think there's anything that can be done on the ISP side.

TraderEyal,

How bad is your lag and how often?
Whole session, early part or news events?
If it's only during high volume periods, could it be the CME lag issue? Not sure if it's resolved yet.

[DuaneG]

I wanted to jump in to touch base on one aspect of this issue. This is likely not being caused by any delay from the CME. We've been working with the exchange over the past weeks and have been able to get this issue resolved. Just wanted to clarify.
