ADX and Range Expansion

["Monte C. Smith" <mcs@xxxxxxxxxxx>]

One of the faults of the ADX may be the potential it has to assign a
"0" value to daily directional movement, even whan the day's range was
greatly expanded. Other factors about the ADX also ignore  intarday
range expansion. True Range indicators would pick this up, based on the
distance from the intarday high to low.
 I wonder what the list's intepretations of range expansion are, and
whether volume forms any part of their study.

Thank you.
