White wave B - 1

The blown-up up-side ABC has finished making white wave A.

We are not having white wave B.
Before of that,

White wave A =  A ( double zigzags, irregulars & zigzags )
                         + B ( double zigzags )
                         + C ( expanding diagonal - the strong upside correction )
White wave B = (above pic) double zigzag (green a)
                         + irregular(? green b)
