Getting max/min values in wave data

[TOKYOJ1]

Hi,

I have a set of data that is in wave format going from positive and negative numbers and positive numbers again.... (which I have marked "X")
How do I get excel to identify these points between highest positives and lowest negatives?

Thanks in advance
TJ
