FWIW: I've seen differences in my *30-minute* bars between Omega's
supposedly-BMI/Signal data and BMI data from a friend's system. The
differences in data were significant enough to result in several
missed trades using the Omega data.
Frankly I don't understand how anyone can expect to trade reliably
using 2-tick bars, given all the things that can happen to data
between the pit and your screen. If it works for you, great -- but I
gotta wonder if it wouldn't work just as well with 1/2 or 2x as many
ticks. You're already guaranteed to lose huge numbers of ticks,
what's a few more?
