NXE (Uranium play) bull flagging to set up coming +/-20% gains

I bought NXE today at 4.05 after seeing this nice bull flag setup. I am targeting 5 as a sell target, approximating at 20% gain from my buy point, which could be undercut on Monday. Notice two days of significantly increased volume: 1st on attaining a higher high on 7/27, than again on 7/29 representing the breakout and follow through from the down sloping trendline. Additionally, NXE has been out pacing the S&P 500 since its (NXE's) closing low on July 5th (comparison not shown on the chart). Could be a sign of things to come.
