Nice to meet you. I am currently working on my eBay dissertation, I am gonner examine buyer and seller behavior on eBay UK through analysis last bidding, winner's curse and buyer feedback. I am facing problem of collect data of later bidding, and positive and negative feedback. If i will collect manually, that will cost lots of time.
Although eBay's market data scheme includes bidding information, I doubt that any of the subscribing companies (e.g. Terapeak, DeepAnalysis) will make use of it, as it isn't that useful to sellers.
The option that leaves you with is getting a programmer to "scrape" eBay to obtain the data you want. This is the same technique used by sniping programs and unlicensed market analysis software, but it is frowned upon by eBay. Perhaps your college's computer science department could help you if you decide to go down that route?
