S&P 500 (SPY) Inside day, which lines up perfectly with a break of the 10 DMA should 277.48 fail.
Russell 2000 (IWM) 157 pivotal all around. And especially on a weekly close. With that said, a close under 156.50 should bring in more selling.
Dow (DIA) Inside day. A break of 258.77 corresponds with a break of the 10 DMA
Nasdaq (QQQ) Missed an inside day by one tick. Yet, a break of 171.76 is noteworthy since it will break prior day low and the 200 DMA.
