This is what i'm thinking based on Elliott wave. Assuming we're in wave 1 at the moment and we have a target of 697 ish then according to fibs and resistance levels, this is what i've come up with...
Not sure what happens after 697, but the bullish case would be that we come down to the trendline which would be between 620 and 640, then back up for another bullish assault.
Bearish case would be that we sell off after 697 and break trendline supports and deep dive to @DanV's targets towards 200-300
