This move has now pushed shares of GLUU into breakout territory, since the stock has taken out some past overhead resistance at $5.18. What's bullish about this breakout is that the volume today is already surpassing its three-month average action of 2.7 million shares. Traders should continue to look for long-biased trades as long as GLUU is trending above $5.18 with strong upside volume flows. I would consider any upside volume day that hits near or above 2,691,100 shares as bullish. If we continue to see that action, then GLUU has a great chance of re-test and possibly taking out its next major overhead resistance level at $6.10. That $6.10 level is the 2011 high for GLUU.
