A good strategy would be to buy gradually every time it hits the lower side of the last triangle. Don't wait too long though, the breakout looks to be enormously bullish!
At least so far, the movement in the last triangle seems to mirror the movement in the second triangle.
[Basically all were already established in my earlier post, written before the most recent bounce up to 1200. I am surprised how accurately these lines continue to form supports & resistances in the last triangle.]
