my initial count thought there was
an extension from the 1st and second waves
hence (i) and (ii)...
3rd and 4th waves are not required to be
labelled with extra numbers as this part of the
corrective wave structure is more complex so
we have 'alternation' or difference in
structure between the two corrective waves...
google elliot wave theory and will 'get' what
i mean...
