Differences between Qcharts 5 and ESignal 7,6

[syswizard]

Guys - I have searched the forums for the issue of comparing Qcharts to ESignal and have found nothing significant. I am currently a Qcharts user thinking of "jumping" to ESignal. Can anyone outline the differences ? My big concern is the built-in scanners in Qcharts 5 that provide for Nasdaq stocks: unusual volume & trade-rate scans that I find invaluable.
Thx !
