For each game there will be something like this:
10/11,10:55,AM,+5,+100,-5,-110
10/11,10:56,AM,+5,+100,-5,-113
10/11,10:57,AM,+5,+100,-5,-110
10/11,10:58,AM,+5,+100,-5,-113
etc...
You'll have several of these for each sportsbook. Then you'll have all the games.
Right now I'm thinking of having separate csv files for each game.
Within each file I'd like to line up the odds from different sportsbooks by time, but they don't put out odds at the same time so I was thinking of putting each minute in one column and then just fill in the odds. Doing it like this will take up more space. I don't know maybe I'll try to think of a way to search without having to actually do this minute by minute.
Ah, maybe I could search for the datetime, and if it's not present decrement the datetime until a datetime is present. From here I can get the odds next to the datetime, and they should be the same odds available at the time originally wanted.
