Difference in market breadth quotes between various rt data vendors

[MT <mtzianos@xxxxxxxxx>]

Hi list,

I've been monitoring various systems (incl. OB, thanks MB) that use
market breadth (advancing, declining issues etc) and noticed that they
signal at different times, depending on which feed is used (eSignal or
DTN in my tests).

The difference seems to be quite substancial, so I wonder if anyone has
looked further into the cause of this.

Regards, MT
