I'm hoping someone may be able to point me in the right direction with this, and to anyone who does, I greatly appreciate it. I want to be able to backtest previous games within my own statistics to see the highest prices matched in-play. As we discussed, there are huge swings in NBA. In the picture below and spreadsheet attached are predictions that I currently do not use due to it not being profitable. BUT If I can test at what point they are profitable along with the likelihood of being matched then may be able to make them profitable. As you can see, its -0.89% POT from 2772 games over 12 seasons on corporate/vegas odds (I get my data from bigdataball and they use vegas odds) So Betfair can beat those odds anyway, but knowing ratio of the likelihood of being matched at X odds can make these profitable. So is there a source that says the highest matched prices of completed markets? I tried to get data from https://historicdata.betfair.com/#/home but I couldnt get the file to work at all. If anyone has any helpful info on getting data or even to get the bloody file to open I'd greatly appreciate it!
