Finding local minima and maxima of a graph

How many data points are you talking about?

Also, are you using this for forecasting, such that you would need to do a regression analysis? If you are wanting to make predictions, that changes a lot.

As for detrending - that seems unnecessary if you are looking for fairly local mins and maxes. 

I think you might find the rolling average approach reasonably fast. I can help with the algorithm, if you need.

Jonathan,

Sure, that approach can work. But it isn't terribly efficient. It would 
however be less computationally intensive if I detrend first. That's the 
first step. So if you have a notion on a least squares linear fit line, 
that would be most welcome.
