I think it was Seq that first mentioned what looked to be an inverse head and shoulders pattern. At the time i couldn't really see it but after todays move the pattern has become alot clearer.
As a rule of thumb the proceeding move is approx the distance from the head to the neck line repeated - similar to the pennant trout showed earlier.
Here's a link to anyone interested
EDIT
And here's a rotated and flipped chart to make it cleared.
