Possible Ascending Triangle formation is violated now and has mutated into a Double Top in the making.
If it breaks through 4800 to 5000 range, then a retest of the local lows at 4500 and 3700 might be in the cards over the next week. It could even go lower than 3700.
Only thing that can be said now with any degree of certainty is that the weekly will most likely not close above 6300, which is what would have been necessary for the quick capitulation narrative to play out. That is, unless it rallies 1000+ points in the 2 hours between the start of CME trading at 17:00 Sunday CT (-0500 GMT, so that's 22:00 GMT) and 0:00 GMT Monday. Anything can happen.
