I *think* you're misunderstanding what MB is doing. Take a look at
http://24.0.100.173/traderwarex/multitick11.gif . Look at the green
(ES99U) and magenta (SP99U) lines.
Notice the last "bump" in the magenta, starting from about 11:15 on
the time scale. Compare the low (about 11:15) and high (about 12:12)
on the magenta line to the low and high of the ENTIRE green line.
That last "bump" in the magenta corresponds to the ENTIRE green line.
Why? Because ES has a lot more ticks than SP, so it's going to have
more bars for the equivalent time period. And MB's chart DOES NOT
use the same time scale for all data series. If I'm not mistaken,
this chart displays essentially what you'd see if you stacked three
TS4 tick charts on top of each other, with equivalent bar spacing.
Each chart would have a different time scale, but they would all line
up with "now" at the right side of the chart.
I'm not sure what happens if you scroll MB's chart, but presumably
they've worked out the magic so that the "now" at the right side of
the screen lines up, even if you change the "now" to another time.
I'm still not quite seeing how you make use of this -- why is it
helpful to have ES and SP displayed with different time scales? --
but it's certainly not impossible.
