Is there any free software available or service that will collect betfair odds movements.
I have started to collect a couple of markets tonite laboriously. Ive got 2 monitors so had two Betfair windows open to collect data from both the Fiorentina and Santander games. I took screen shots every 5 mins of the C/S, MO's 1.5 and 2.5 markets.
Just used the print screen option and pasted into publisher to crop out the garbage
Easy to do but you need to be at the screen for the duration of the match.

I know this wont answer your question but i do think with football there are so many variables that its almost impossible to say where the odds will move to exactly at any given point of a match, even if you had 1000s of stats from matches.

All we can really do is try and get a general idea of where it will move to and so you might be better off with soccer mystic or just from experience?

Might save you hours of trying to collect the data, unless you can find the software.
