IWM looks bearish to me.

I have been looking at various charts in the futures, and I see the IWM, Russel 2000 ETF, has the largest gain since the March crash. The index has gained approximately 118%, with minimal corrections along the way. I looked at the weekly chart, and I see wade rising wade is forming. That tells me there will be an imminent correction of 20% or so soon. If we see a 20 % pullback, it would be a healthy one for this rally to continue, but anything above 20% may cause a lot of damage it the small caps.
Please, let me know your thoughts.
Thanks,
