BOEING - BA Technical Analysis

Based on some simple Technical Analysis it seems that the upper trendline of the channel (dotted green lines) has been broken giving a potential buying signal.
Before Buying (for a short term investment) wait that the prices will start moving upward (they can still go down a little bit using the upper trendliune as support)
Furthermore, prices are still moving inside a channel (top/bottom dotted red lines) and the idea is that prices are in the really stage to reach the upper trendline.
