Although there is support for IWM between 182-1, I think the real target will be the combination of the monthly BB and 100 ma, around 158-156. Structural trendline (purple) looks right and it's no surprise it showed up at the 18ma exactly to regect the advance.
IWM divided by SPY is a bull flag, so I expect IWM to sell off much more than spy once it breaks out - which looks to me like it could happen this month.
Good luck!
