It can also be a flat correction followed by a w1 that is still correcting. Be carefull when you have a 5 wave down followed by triangle, could be the B of an abc correction, in that case it's bearish ...
Or maybe correction of w1 done, and we're at the end of correction of sub wave 1 (so subwave 2 = triangle), in that case it's bullish ...
I won't bet on it until I see a break of triangle, and maybe some higher highs, but just my opinion, interesting analysis anyway :-)
