This is a chart worth taking a look at for your reference due to the aggressive breakout of price through the horizontal resistance line. One of the things that many traders look for in this type of setup is a decline in volume in the development of the pattern and then a volume spike when the break occurs - you can see how big the just is relative to the volume that has come before it.

This type of breakout may frustrate some as the price has already moved a good way toward its target price but as I say its always interesting to see how closely some charts go to obeying the expected 'rule' of a pattern like this.
