Alun, you made me think:
If I want results, such a graph and statistics about deviations from the norm, or increase or decline,
what programming language and platform would you recommend to me?
To give you a clearer pic what I would like to research about:
This guy who focusses on swing-trades seems to compare cycles:

and maybe later even compare more than two time-spans.
Since I start from scratch I still am open to any paths.
