I use an enhancement on the PE ratio where I take the average earnings over the past X years (between 5 and 7 usually) instead of just the most recent. That can accommodate short term fluctuations in an otherwise stable business.

Also the rate at which the dividend changes is important.

Unfortunately it is scraped from various sources on the web so it cannot be used commercially

Intersting idea, will add it to the list of potentials

Unfortunately no, its purely the prices at the off which I have available. However I am planning on monitoring future races to see how their prices change over time

That is one of the plans I have in mind

Good idea, Ill create a torrent once I get the chance

See if theres a local group and go along and talk to a few people. I'm sure they'll have some stuff you can get your hands dirty on that will at least get you some experience in the field
