A complex correction not a surprise given the simple correction in the currently labeled wave-2 of this extension. I'd start with a portion at the first box and look for a second add at the lower box at the 50%.
8-to-1 on the first (if it holds) if stopped out your 'get well' trade is below with a 3-to-1 risk/reward. You need to give it more room on the second entry so keep the size appropriate to your trade plan.
