GVT wave 4 correction - how much further?

so we are still correcting on wave 4 and what looked like would hold at 24% took a nose dive to the 38% and even sub 50% levels.
drawing a strong line at 0026 as this is a good support area and we bounced right off it similar to the way up on wave 3.

question is do we retest this level again (0026-0027) or are we just about peeping out enough at the upper resistance line? either way a bit of volume around this area and we could easily break out into our 5th wave and on to all time highs.
