How can Grasshopper collect the local peaks and valleys of polyline in a continuous way?


As the pic show, I have a polyline, with peaks and valleys. I want to collect the peak and valley points in a continous way (point 1, 2, 3, 4, 5…). The Rhino file is attached.

Any suggestions and ideas are so appreciated!
