Hi,
When Up-down hill wave is pointed with valley marker in rectangular Graph, it searches and sticks to some of valley.
And using cursor key, it moves. But after pushing cursor key some times, it stops moving and sticks to one of valleys.
Just reporting,

Peak / Valley detection is based on a "sliding aperture" algorithm. The defaults are good, but sometimes need to be adjusted, depending on the data. (Sometimes a small peak is ignored, noisy data creates too many insignificant valley stops, etc.)
Try adjusting Marker's Properties / Aperture Height & Width. The defaults are Width=10% and Height=5%. Note that this is actually a global setting, so the setting is retained for future sessions.
From Genesys Help (on Markers):
Peak/Valley detection works as follows: The "aperture" window is a box that is used for peak / valley detection. A peak or valley must be at least as large as the box, otherwise it is ignored. In general, a user should never need to adjust these, as the defaults are pretty good. A local maximum can be rejected by increasing the aperture window. Small peaks can be detected by decreasing the window size. The same criteria are used for valley detection (with a sign flip). The parameters are percentages (which are scaled by the bounds of the graph) and then used to evaluate candidate peaks / valleys and reject those that are too small to be of interest.
