As to the number of potential observations. Thousands of series, 10s to
hundreds of thousands of observations per series at a minimum. Possibly
millions. So computational efficiency isn't a luxury, it is a requirement.
Yes, absolutely, detrending is required. I won't go

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.
Yes, what Jonathan wrote.
The folks who do heavy computing in the audio world do something called
windowing. Thats like a rolling average, except weighted toward the "center".
Choosing the width of the window and the algorithm for determining its shape
can get complicated, and has been greatly
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.

Hi Bryan,
The first step is to define a local minimum or maximum for this situation.
Plotting a 3-day rolling average would be pretty straight forward. Is three
days sufficient?
You could get a 5-day rolling average, then pick five day averages that are

Yes, that would be far too many hits and there has to be some scaling

For example, is the peak or trough 3 percent or more away.

Peter, Jonathan
I had thought to use a sin function on the time series to find peak and
trough values. I would filter the sin function results for those close
to 1 or -1, though I am not sure what the filter interval will be just yet.
Then, I would be able to grab the value from the actual ti

Hi Richard,
There is no workaround. This simply doesn't work. Let's hope that the unicode
overhaul in 4.5 changes this.
However, you can use AppleScript or VBScript and create a complete parallel
