Quote from eSignal Support:
Unfortunately, we don't currently provide that heading. We are in the re-design phase of our Quote window so this is a good time to get lots of user input. Can you elaborate more on this field type? If you have other suggestions, feel free to email product development directly at ideas@esignal.com
Thanks.
It continuously shows the % in range for a giving security. For instance if msft was off 50% from its intraday high it would have a % in daily range of 50. If msft was off 60% from its daily high it would have a % in daily range of 40.
Both Quotetracker and QCharts carry this column heading field so its nothing new.
Highly useable though.

Actually, several customers requested this format and it was fairly easy to program.
