That's a trick question, whose answer depends too heavily on the kind of data 
you're processing. 
* Are you expecting some kind of trend ? If yes, detrend your data first and 
work on the residuals.
* Are you interested in finding the breaks in trend and/or regimes ? If so, I 
can send you some algos that do just that.
* Are you interested into finding the outliers ? There are common approaches, 
some based on an expected normality of the data, some based on more robust 
methods... Googling 'outliers robust method' should get you started.
