Minor Subwave c
Rather belatedly, it looks like Minor Subwave c (black) has started. However Minor Subwave b has dipped slightly below the bottom line of the diagonal. This makes Minor Subwave c having to make a long way up to the top line of the diagonal. It is not necessary for Minor Subwave c to touch the top line of the diagonal, but it should be near enough to convince us that the diagonal structure is valid. If this fails then there are two possibilities. It could be that Subwave 4 did not end as shown in the chart, but ended at the bottom of Minor Subwave b. Thus Minor Subwaves a and b are a continuation of Subwave 4. The other possibility is that the whole wave count is invalid and needs to be revised. We have to wait to see how the wave structure further develops to make a conclusion.
