You're on the right track, although I wouldn't call it a quadruple bottom, it's one double bottom with a secondary smaller double bottom (which strengthens the first). It's an Eve/Eve base.
Yes the 61.8 held however it's run from its 200 to the 61.8 in 3 bars, that's something to be concerned about.
Let it prove itself before rushing back in imo.
