The Aug - Oct decline is ambiguous to me

The move down from Aug - Oct is iffy, it's come down in five semi-equal legs but I can't see it as a WXYXZ pattern.
I am inclined to think that (in this overheated market) this was a three waves down and now we are finishing a three wave running flat as B wave.
To finish this larger ABC off, now will come a three-ish month leg down for EOY tax loss harvesting.
