The ascending triangle is one of my favorite chart patterns. To confirm a breakout, we need to enter the corner of the triangle and then break above the previous high that forms the top of the triangle. A confirmed breakout usually results in a move about half the height of the triangle, or about $9 per share in this case. One nice thing about this chart pattern is that it allows for a fairly tight stop loss. If we breach that lower trendline, the pattern is broken and we can exit quickly.
