I hope the image is posted here, but if not I've included a link.

I think the picture shows the problem. The daily volume, chart on the left show 3 million shares traded on the day in question. The 4 hour chart on the right is totaly incorrect as it does not account for the 3 million shares. I've never encountered this problem before. The stock is IMO.to

I can over look the issue with the slightly off shading of the two 4 hour bars, marked by the crosshairs on the daily chart.

Thanks for checking this out.

I have forwarded your report on to the data department for further review.

Not sure if it was late reported activity or what, but the data matches all other sources we've checked. Intraday volume totals around 330k but daily volume is 3M.

There is a chart option; on a chart, right click, edit chart properties then select Pre/Post Data.

I've played with the chices but sadly I'm not seeing anything change.

Would it be possible to have all premarket trading volume added to the first minute of trading volume. And have all the post market volume added to the last minute. Doing such would eliminate this 'missing' volume for me. It is central to the way I trade.

Thanks, for your efforts.

Thank you for your suggestion.
