Will QQQ maintain support at 200dma and September highs?

On 9/17 QQQ established 108.73 as resistance when it reversed off this level. At the time it closely coincided with the 50dma. After breaking through that level on 10/22, 108.73 has since acted as a support zone. Today is an important test of that support and its one we should keep on our radars. Furthermore, should QQQ successfully hold above 108.73 by the close, it will have created a "support day" by closing in the upper half of its trading range and on above average volume.
