Tool for scalping Betfair Exchange

The idea is to create a tool what prices should be around at any given moment of the match, based on other markets. In betfair, the most liquid markets are Match Odds and Over/Under 2.5 goals. Based on these markets, one can derive the price the other less liquid markets should be at, like correct scores, under/over 3.5, etc Once taken this into account, one can create a sample of historic matches with same odds and see where their prices where at, and create a tool that shows you that in real time. Example, say historic data says price for over 2.5 when score is 1-1 at 70th min of the match is 2.0 but the price in the betfair exchange is 2.5, then there is a discrepancy and one can take advantage of that. Is that something you can do? I am looking for a partner!r!
