The music of the stock market

Over this weekend, I have come to realise just how similar the music is to high finance (and that I should take a day off occasionally!). I love the range of applications that I look at ... and on Saturday, I was looking at sequences of stock values at regular intervals, whether they were going up and down over periods, and other factors such as percentage changes and how erratic the movements were. On Sunday I was dealing with the music of composers who's names were new to me, but well know to my delegate, and looking at their ups and downs, rates of change, and how erratic they were.

In fact, it took me a few hours to "twig" the connection ... and its struck me like a bolt from the blue when I realised that both my city-type and my musician had split their data sets into bars of a certain length.

Today was Python, yesterday was Lua, and tomorrow will be C and C++; I don't know the details of tomorrow's application, but even if it turns out to be web log analysis, I expect we'll be spitting our data down into a series of equal length periods and looking for trends between them.
