What is OttaBid?

In any auction, there is a distinct relationship between the bid value and the probability of winning the auction with that bid. As the bid value increases so does the probability that the auction will be won by a bid of that amount. Ottabid calculates that relationship based on data from completed auctions of similar items. The relationship is communicated to the user through a graph. Furthermore, the user can specify a desired probability of winning and Ottabid will suggest the bid which will have that probability of winning the auction.
