I am getting bad data for the above calc symbols real time. If I refresh with historic tick data that is ok with changes every 5 seconds. In real time the ticks change very slowly and there are a lot of missing ticks. I get this on both 148 and 156 servers. Please check this. Thanks.

Hello John, I am not seeing any issues with these symbols on my end what software are you using and what is your login ID?? It may be a setting in software causing this. Also is there any way to send me a snapshot of what you are seeing on your screen?? What type of chart are you looking at tick, minute, daily??

Thanks.

My login id is 202144. I am using Invest RT. The difference between real time and historical ticks is extreme. You can see it in 30 second bars or the quote stream. The historical ticks change every 5 seconds whereas the real time ticks are not matching. They are changing much less frequently and there are many missing ticks. This started happening yesterday afternoon and has continued for me.

I have been on chat with Loren Foster. He has sent some data to be analyzed for the inconsistency so someone may be on this already

Hi John,

Our developers are working on this now. There does appear to be some sort of issue with the TICK.Z, they should have this resolved shortly.

Thanks,

Sarah

thank you. Please make sure they check TIKI.Z and JT6T.Z as well.

I am still seeing issues here, how is the repair going?

The operations are still working on this issue for a more permanent fix.

Are there any servers where the streaming TICK.Z indexes work now?

John
We are still working on resolving this issue with the Tick.z and other symbols that work the same.
Can you send me a screen shot of what charts your seeing so I can compare the charts/data with what we have in IRT, MD and DTNIQ
Thank you

Here is a 30 second ES and JT6T.Z chart with the real time streaming JT6T.Z ticks. I'll send the historic refresh chart with the correct ticks shortly.

John

The JT6T.Z after the refresh. This is what the chart should look like in real time. As you can tell, the current real time ticks are useless.

John

Here is the streaming TICK.Z chart with the bad ticks.

---

John

TICK.Z with correct ticks after refresh. Let me know how the repairs are going please. These indexes are one of DTN's strong points as they are accurate and calculate every 5 seconds. They also have worked well for a long time. I hope you can get them repaired soon.

I was out yesterday and when I returned I found that the calculated indexes problem still exists even with the new beta IQFEED sadly (today as well). The streaming data for these indexes comes in at about every 15-20 seconds. I have sent a before and after for the TICK.Z index superimposed for a direct comparison. This problem seems very strange for the reason that all the other 130 instruments I follow work fine with zero lag even in fast market conditions. Even the EM-PREM.Z which is also a calculated index works fine. All the indexes that are calculated from stocks such as advance decline indexes or tick indexes are affected. These indexes normally send out a tick every 5 seconds which should not be a problem. Would you please inform the tech team of these details? Thank you.

John, thank you for your diligence in this matter. I assure you we are continuing to look at this issue and we will come to a conclusion. The reason this is taking so long is several inconsistancies with testing methods trying to duplicate this as well as other issues (unrelated) appearing during testing which have to be isolated before continuing.

I will hopefully have a better understanding of the issue after Monday's round of testing and be able to provide better feedback for you.

Thank you for the update.
