Quote from SK0:
Pace Acceleration was a concept created by Spyder. Rocket was a term used by Jack way back in 2003 to define Traverse-level trends where the 5-min bars exceed 10,000 contracts each (probably too low for our time now).
A Rocket could look like a Tape but it is not. The non-dominant Tape component of a Rocket could move in dominant direction too. I know it sounds incorrect but I never make it up as that was what Jack said in some of the old posts.
I searched for the rocket's information in ET and read the "beginner rockets.doc", but the information here is quite brief.
Jack mentioned rocket in this thread:

but not much details.
Where can I find more information?
