eSignal 8.0, 8.1 & QCharts

javs,

That is definitely abnormal behavior for eSignal. I would suggest checking in with our support team, so that they can troubleshoot the issue with you. Here's a link on the ways that you can contact our service department.
 
Jay,

Can you answer my question from a few days ago? Thanks.

Quote from Chuck_T:

A lot of the software that we are working on for the last year is on the server level.

We have been re-engineering to multi-threaded 64 bit systems with dual dual core processors as we deploy hundreds of new servers on to our server farms.

This is a multi-million dollar investment in our future to handle growing trade and quote volumes. This along with the investments Comstock, a part of our company, has made in international data which we use and our parent IDC has made in new computer sites will benefit all our users.

Jay,

Wrong message ... here is my original question. Thanks.

Quote from Van Halen:

Chuck,

My concern is the intraday volume data issue not being accurate. I have been fighting this one for the last several months.

I have written so many custom indicators with esignal that it will be a pain to switch providers and redo all of my work but I am on the verge of making that decision because I am unable to trade reliably when the volume data is inaccurate.

Will esignal commit to this issue being resolved in the 8.0 releases?

What type of intraday volume are you talking about? I haven't noticed any problems myself, but may not be looking as closely at volume as I should. I'm addicted to their EFS, so can't see leaving esignal, but want to understand if there's a problem with volume that I should be aware of.

Thanks
 
paulelly1962,

The problem with volume exists and has been acknowledged by esignal, at least on the emini contracts. If you go to their support forum you can find several posts on the topic.

I have also spent a great amount of time writing custom efs code that I hate to abandon but with the current issues and the way my indicators use volume to make trading decisions I am preparing myself to move on.

To see it for yourself, load up a volume chart (ex: 500v) in esignal during market hours. Let the chart paint for 10 or 15 minutes. Take a screenshot of that chart. Now, hit reload chart. Same time frame, same everything, chart looks different. Sometimes not as bad as others but different. Depending on what your custom efs indicators are, you may be in or out of a position you would not have been in had your system seen the real volume.

It is also apparent when downloading and playing back the daily tick file. Compare that against your screen shot and you will see a different chart also. Not drastically different but enough to cause several entries / exits to fire which should have never happened.
 
Thanks for the info. I set up a 500V chart on the mini and made some arrows on a large portion of the screen which pointed to the high and low points of the bars. I left it running for about an hour and then refreshed the chart. 5 of the bars now had a high or low that were 1 tick off, but the new placement was at a level that matched the bar next to it. I can definitely see this as a problem, but none of the strategies I use are dependant on this type of chart. I've never made a shift to volume studies and and concentrating more on price patterns.

I wonder if this is related to insertions and deletions. If they're really going to add them to the charting, that may clear up these descrepancies you're seeing.

Cheers,

Paul
 
Chuck,

The insertions / deletions make sense. From what I understand the problem is also caused by some of the data being timestamped incorrectly, right?

That would also make the charts appear different (high bar really happened a minute or two ago but I received it two minutes later) which would cause my chart to paint differently live compared to end of day when the timestamps are corrected.
 
Boy, right or wrong, you guys are lucky to see any
volume!!

When you have a volume spike, the bars that follow
are shown only as specks. When you drag the volume
scale up to expand the bars, the bars do expand
but at the same time they go down below the bottom
border of the volume pane and are no longer visible.
If you could then put your pointer in the volume
pane and drag the bars up as a whole in their
expanded state, that would be fine. But that function
is not available in the volume pane as it is in
the price pane.

It would seem so simple to add the same adjusting
function to the volume pane that you have in the price
pane, or even just an expand/contract icon. All first class
charts, and even most free software, allow you to adjust the volume bars.

Will 8.0 include any improvements?
