Hi. After a Minute wave 2 (green) that was deep (78.6%) and could have had a sideways shape(zigzag-flat combination pattern), we could have had already a complete Minute wave 4 that was shallow (23.6%) and displayed a sharp shape (zigzag pattern), meaning the 2-4 alternation guideline for impulses would have been verified perfectly (in deepness and shape).
If that's the case, then Minute wave 5 is underway, which target is proposed in the chart.
Overall, this plan suggests an ending diagonal is underway, as an alternative to an impulse. The ED pattern would resolve the problem of not being possible to draw an EW channel containing the impulse.
