Volumes are off

Recently, I compared multiple volumes over 30 min periods on the SierraCharts to the volumes on the CTS T4 graphs and I noticed discrepancies. Some of the volumes on SierraCharts would be over or under by 1 to as much as 700 contracts over the 30 min period. Since I download from CTS, should not the volumes on SierraCharts match the volumes on the graphs CTS provides? For the most part the volumes match, but every once in a while I experience this mismatch and I usually just delete and download the data again and that takes care of the problem, but I wanted to know if this is normal. Also, my internet service provider notified me that I was getting a weak signal which would cause my connection to drop sometimes. Could this be the cause? However, if the SierraCharts got disconnected from the data feed would it not just reconnect and download from where it left off? At the very least, the log would notify me if there were disconnections or timeouts, right? So, if I downloaded data and there was nothing in the log about disconnections, I would never have to worry about that data being inaccurate, correct? By the way, I can still replay the data with the incorrect volume so I definitely have tick data I am just getting too much or missing some for a particular 30 min period. Thanks

It is not normal, and we would not know the cause of it. The issue would be external to Sierra Chart. A poor Internet connection might be the cause. We would not know because we do not control the data feed. You also need to understand in the case of T4 at the present time we are still using the client-side API component and what it does internally, we have no idea. It's a black box. So many of your questions we do not know the answer to. The connection is being changed to a direct FIX connection. More about this is explained in help topic 76 here: Http://www.sierrachart.com/index.php?l=doc/helpdetails76.html One reason we have posted this information in help topic 76, is to encourage changes in this industry, because these API components on the client-side, make no sense and we cannot properly support our software by using them. They create all kinds of negative side effects. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

So the CTS T4 connection is being changed to a format you would support? When? Or will I no longer be able to use this data feed with Sierra Charts in the future? If so, when would you stop supporting it?

Yes, we are going to be updating it to use FIX as we said. So you still will be able to use it. Sierra Chart Support - Engineering Level Your definitive source for support.

SC Support, The volumes are still off. I am now using CTS FIX SC v1010. By the way I have narrowed it down; this only happens during Real-time Intraday Chart Data File Updates. The mismatches are easily fixed by deleting and downloading data and I never get the mismatch from downloading past data, only from real-time streaming data. Additionally, I have contacted my ISP and my signal is just fine. Also, I have updated my exceptions list on my anti-virus to exclude just the entire Sierra Chart folders (rather than excluding each .scid file individually), but I don't see why this would matter since I do not use scheduled scans and I never scan when SC is open or downloading.

Wow that was fast! The 30 min volume bars have different volumes on SC and T4 platform. The volume is always less on SC, therefore some data is not getting through. I will admit that since FIX this is far less severe, both in magnitude (volumes before would be off by 700 contracts on ES now the worst is only 50-100 contracts) and frequency (before nearly every bar in a period of streaming data was off, now only a couple a day). Thanks

Is your T4 using smart / normal buffer ? SC is using Fast buffer. The data is not the same. You need the CTS Advanced package to get fast buffered data in T4. Even then there might be differences that I won't go into on this forum.

Do you mean you were seeing this with Sierra Chart versions that were earlier than 998? Our understanding is that the CTS T4 data is perfect and there is no data loss. Not sure what we could do about this. Does anyone else see this problem with CTS? We will have to do some testing. Sierra Chart Support - Engineering Level Your definitive source for support.

Yes, in fact I have seen this as early as January this year(probably earlier, I just don't have the time to check 30 min bars any further back), so definitely before 998 FIX. As you basically said back in April in post#2 you have no control over this and I should wait for FIX, which is why I waited until now to bring it up again. The Data for CTS T4 is not exactly perfect. After you guys fixed the issue for out of order timestamps, I still got out of order timestamps. Read my Support board message entitled: Out of Order Timestamp. There too, I was told to wait for FIX. I really do appreciate that you are now taking the time to look at this. These data issues have been plaguing me for quite some time now. Thank you

At this point we have done all we can. The integration to CTS FIX is as good as we can make it on our side. Any outstanding market data issues would be on the server side. We have noticed an occasional problem with out of order timestamps when downloading historical data. We have added a filter for that in version 1012. Longer-term we plan to be offering our own CME data feed which you can use as an alternative. We expect that to be out in about 3 months. So our focus, is going to be on our own data feed, rather than the literal impossible task that we have faced for more than a decade now of all kinds of problems that people want us to solve with external data services that we cannot.

So our focus, is going to be on our own data feed, rather than the literal impossible task that we have faced for more than a decade now of all kinds of problems that people want us to solve with external data services that we cannot. I can understand this. However, as you understand, you are going to be providing a data-only feed. If the user's order routing feed as implemented in SC does not sufficiently match the data feed, then it won't matter how good SC's data feed is. There will always be differences in data feeds and I know it must be difficult dealing with them all, but that is the price you have to pay in order to support your paying clients who wish to use these. I am actually amazed at how many feeds SC supports, and wondered why you don't pare them down and support fewer, if it is a burden to do so. My only guess is that there are enough paying clients who use these to justify the cost; otherwise, you would not support them. Also, keep in mind that your new feed is currently CME-only, and there are probably quite a few SC users who use other exchanges, so hopefully your focus on the CME feed will not alienate those users.
