Standard Dev question

[Burga1]

Hi,

I know the command to calculate Standard Deviation works like this:

STDV = StdDev(Close, 15)[0]; //get the SD of "Close" for last 15 periods


I'm having some trouble with doing this for a sequence of numbers. I have 17 values numbered sequentialy (1, 2, 3, 4, 5....16, 17). I simply want to find the Standard Deviation for these. I tried averaging them together and then applying the above command but got an error...I'm having a mind block trying to figure this...any help appreciated.

Regards

Stuff these values into a DataSeries object and then pass this object into the StdDev() method.

OK, seems like that would work, thank you...
