In my "learn something new" series.

I was getting no results whenever I'd put the CMF indicator into a scan. I flipped over to the Predefined Scans page as they have a scan for Improving Chaikin Money Flow. There is zero results showing for the stock indexes when I checked as well. I sent a message to support and they responded


Thank you for contacting us. You cannot scan for volume-based indicators, like CMF, during trading hours. Their data isn't available for charting nor scanning at that time. There's more information on why posted here:
https://support.stockcharts.com/doku.php?id=faqs:why_arent_my_volume_based_indicators_updating

Please let me know if you have any other questions or comments about our website.

I then followed the link, which talks about the chart updating. Not much help there but then I went to the CMF in ChartSchool and at the bottom of the page there is a note.

Note: For the purposes of scanning, daily volume data is incomplete during the trading day. When running scans with volume-based indicators like CMF, be sure to base the scan on the “Last Market Close.” Examples of other volume-based indicators include Accumulation/Distribution, On Balance Volume, and the PVO.

I had never noticed this before. Of course, I don't use any of those other 'volume based' indicators in my scans but word to the wise, if you run a scan during the trading day, and you get zero results, check for a 'volume Based Indicator' in your scan.

I had always wished that they would use the last (whole) trading day, by Default. Rather than Today's Close... etc. That's just me. It would solve all of these problems.

A mention like (* only run EOD) next to the ones that require EOD scan requirement would suffice. Especially the ones that will kill a scan if using the last intraday update period.

that would work too
