Gathering and Modelling Data

[iambic_pentameter]

Afternoon All,

I watched a video on the Bet Angel channel last night and Peter mentioned that he'd gathered a huge amount of data over the years on markets.

He also said in the video that because of the data gathering and modelling (and experience) that he would be able to identify where a price would go in a horse racing market.

My question:

How does one go about gathering that level of data i.e what the price did from when the market opened to when the market closed inc inplay. I currently have the SP Data from Betfair as my main source.

Also, how do you go about modelling that data?

Many thanks
