I used to have an uncle who plotted market fluctuations with pencil and graph paper. He would study daily stock prices, unroll sheets of graph paper and patiently plot changes. He worked as a movie projectionist (this was the 50s) and only had a fourth grade education (times were tough for immigrants when he was a boy). However, my uncle made good money with his conservative approach. Of course, it was a different market then. But still...

I am highly scepticle that this gives useful information during sudden changes

I know nothing about graphs or making money, but my instinct tells me you're right. Respect for being able to do this analysis :)

Also, the kitten is wonderful.
