Incorrect Intraday Chart Volume (Merged)

[khalsa]

Hi there,

I have been with Qcharts for many years now and on the whole happy with the product.

However recently I found on Qcharts 5.1 I was not getting all the volume data coming through on ES. I mainly use 3 and 5 min charts and in reality on 3 min charts you can get volume spikes of 20000 and on 5 min volume spikes of 40000+.

However there were days that volume would be much, much less, when I knew in comparison to charts from Open Ecry, the volume was much more.

I worked out then if I did CTRL ALT N and I changed server to CC-11.sc8, I would get volume fine.

This was a pain for me so I decided to upgrade to Qcharts 6.0.1.1.

Unfortunately this problem persists now and getting correct volume data is still totally flaky and intermittent.

As its now using data manager, I see no way of switch servers. If I use CTRL ALT N to change the continium server, it makes no difference.

This is unnaceptable to me. What do you suggest I can do to get correct volume data effortlessly every day like I should do with any professional package like Qcharts.

Looking forward to your reply.

K

Please does anyone know why this is happening (maybe someone from technical)

Volume is such an important indicator that its vital its accurate.

Thanks in advance.

khalsa, if you are getting the volume off the QCharts Continuum feed, that volume has been compromised for many months.

The volume reported over the Continuum network seems to run 20-40% less than actual volume for ES, depending on the level of market activity.

I have been told by QC Support that the Continuum servers and network cannot keep up with the data flows from the various exchanges to correctly calculate and report the volume for ES or any other instrument at this point.

This is one reason they are abandoning Continuum and moving everything to the ESignal feed.

[mikesch]

Just for the heck of it, I thought I would compare the RTH volumes reported for ES on the QC Continuum feed vs. the ESignal network:

11/5 Continuum 779404 ESignal 1869153
11/6 Continuum 738832 ESignal 1579327
11/7 Continuum 903805 ESignal 2320769
11/8 Continuum 824443 ESignal 2725826
11/9 Continuum 751490 ESignal 2241347

The variance is greater than I expected, possibly due the very high volume levels of recent days throttling the Continuum feed performance down further.

To check the 11/9 ESignal reading, I looked at marketvolume.com,
a volume reporting website. They showed ES RTH volume at 2257329 vs 2241347 for Esignal, pretty close.

I don't watch other instruments closely, so I don't know if these volume discrepancies between Continuum and ESignal feeds exist for stocks or other futures contracts in addition to the ES.

Many thanks Mikesch for taking the time to reply.

Thing is I am on Qharts 6 so I am assuming my volume is coming from Esignal Data Manager?

Yes on Qcharts 5.1 volume became a disgrace and highly inaccurate (never used to be until Esignal took Quote.com over).

So is there a way on the latest version of Qcharts6 to make sure I always get accurate volume?

The sad thing is recently I have recommended many people to Qcharts who have signed up and I feel bad now if their volume data is going to be wrong.

Thanks in advance again.

hi khalsa, I believe that if you are running QC 6.0 and the ESignal Data Manager is also running, you should be getting your data off the ESignal network.

I do not know if the volume readings we see on our screens are calculated by ESignal at their NOC and sent to us across the network, or if our local computers calculate the volume amount from the incoming tick data.

If the volume data is being calculated on your local machine, and you are still seeing inaccurate volume readings even running on the ESignal data, perhaps there is something amiss in that local process.

This might be something for ESignal support to help you with.

[khalsa]

Well once again a big thank you Mikesch for confirmation of my problem.

I run a Core 2 duo PC with 2 GB of ram, etc, etc and always have a CPU monitor running so even if it calculates it my end, it should handle it.

So it seems like the darta being received is not accurate for whatever reason.

On Qcharts 5 if I used to switch to CC-11-sc8, it used to solve the volume problem, which indicates to me its a problem clearly their end.

I have not spoke to technical re: this as whenever I phone them, they really are not very helpful in solving problems.

I may have to move on from Qcharts if they cannot solve this, which will be a shame after all these years with them.

Does anyone from Technical view these forums?

Incorrect ES Volume when Using All Sessions

I am running a 1 minute ES chart with All Sessions enabled.

The volume readings are dramatically different than the same symbol, same time frame with All Sessions disabled.

The ES volume with All Sessions turned on is more than 2X the volume with All Sessions toggled off.

Check it out, just toggle the All Sessions on and off and watch the Volume histogram change.

QC, got to get this fixed, can't have bad volume readings if you want people to trust the software.

Anybody else see this?

[khalsa]

JayF or anyone else re: incorrect volume for ES on QCharts

I started a thread below re: problems I am having on volume (please see below in this thread)

I have introduced many people to Qcharts recently and they are all ringing me complaining of incorrect volume on ES being received.

I already know of this and can clearly see its wrong.

When I was on Qcharts 5.1 and I would switch servers to cc-11-sc8, the volume used to be fine.

How can I get the correct volume in Qcharts 6.0.1.1

This is very important to us so please I would at the very least appreciate a reply.

Thanks in advance.

Totally agree my friend and yes I am getting what you see also.

I have specifically started a new thread for JayF, so really hope he responds. We need to know what the deal is here as volume is 50% of my TA.

Thanks all for the posts and the conversation about this important bug report. So far I haven't been able to duplicate this problem... see attached. I will continue to try to duplicate this, and will let you know if I find something.

(I'm going to merge all these threads together to clean up the forums a bit.)

[mikesch]

Jay, thanks for the reply.

You may need to start the All Sessions chart in the premarket and let it run for a while before making the comparison.

During today's high volume in the ES after 3:30 EST, the discrepancy between the All Sessions and non-All Sessions volume was very clear, like 2x higher in the All Sessions chart.

However, from time to time, the volume differences change in magnitude.

For example, right now the 15:41 bar in the 1 min ES #F All Sessions chart shows volume of 17,514 while the non-All Sessions shows 16,126.

Now, I switched it again, and the difference has disappeared.

Is the volume being calculated on my local PC, or is it a number that ESignal sends to me already calculated?

Perhaps this animated .GIF will illustrate the ES (and other syms) volume issue.

The copy of 6.0.1.1 was started mid-day during market RTH.
One may have to let QCharts run awhile before it spontaneously decides to go whack.
If running awhile with All Sessions and then volume has gone whack, toggling to RTH will pull in a new set of historical bars and then toggling twix RTH and All Sessions will show the differences.
So, this is about QCharts just going nuts locally....maybe.
There was this interesting post in the eSignal forum today.

Here's 6.0.1.1 and eSignal running concurrently. I can't get ES realtime in eSignal, so used YM which I do get realtime in eSignal. I see the same issue with ES in QC 6.0.1.1, as reported by others. Trust me, the eSignal chart was matching QC 5.1 that was running on IP4 feed.

As a companion to the previous post with the YM animation, here's toggling twix ETH and RTH chart for ES. Notice the volume study bars and especially the scale flip from 10K to 40K.

[mikesch]

Yes, Larry nailed it, as usual

His ES animation captures the exact issue I am seeing, except that in my case, the All Sessions chart had the extra-high volume readings, while it looks like Larry was getting the high volume readings with the All Sessions disabled.

Thanks for the super example , Larry.
