Hey I'm a beginner in mathematica and I'm trying to code a little something but can't seem to be able to make it work... I know its pretty basic and that's exactly my problem since the mathematica help is a bit overkill for what I need. I have daily stock prices for a stock on a 100 day period, I want to compute the standard deviation for a rolling 10 days period for the whole list of data. So basically, I would like to do something like this : stdev(1;;10) then stdev(2;;11) until stdev(91;;100) and get the results in a list Id also like to get it another way, by starting with only one observation and building my standard deviation calculation until I have my whole rolling period built up, for example : stdev(1) stdev(1,2) stdev(1,2,3) until stdev(1;;10) then same as before, roll the period until the end of dataset and produce a list of the results. Thanks for the help, if what I wrote is not clear enough let me know, Ill try to explain it in more details!
