I will stick with 869 as the (X) wave low until proven otherwise. However, I admit, I don't have superior confidence that this low will hold. I am in a wait and see mode. I would still rather see the market hold above 840 if a final P2 new rally high is to take shape this summer. So my 30 minute chart has an interpretation that would allow a move under 869 and also hold above 840. Call the whole thing a triple ZZ down from 956 (although it could also look like a double in reality - no matter - you get the idea of the moves).
The 1 minute chart interpretation supports a bullish move to backtest the H&S neckline. How the market deals with that backtest will be the key to the next set of market moves of course.
So 869 still makes a decent (X) wave low. If not, then my imaginative chart might play out in some form or another. That blue W - X trendline may point the way.
