Yes, "Rotation Factor" and ideally also "TPO count" which is defined in Jim Dalton's book as:
"The TPO count is found by isolating the point of control (the longest line closest to the center of the range), summing all the TPOs above it and comparing that number to the total number of TPOs below it. Single-print tails are excluded from the count." (page 42, Mind over Markets) Page 43 contains a graphics explaining the procedure.
The "TPO count" is used to determine if buying / selling tails were responsive or initiative. Essentially it gives you the ratio of TPOs above vs. below the POC (minus single print tails)
