Re[2]: Strategies testing. Datafeeds differ a lot

[Jim Johnson <jejohn@xxxxxxxxxxx>]

Hello MT,

I watch both eSignal and Quote.com all day.  The Adv and Decl issues
as well as volume is always different.  I think it is because eSignal
ignores issues below $5 whereas Quote.com apparently includes them.


Best regards,
 Jim Johnson                           mailto:jejohn@xxxxxxxxxxx
