Subscribers can review and download Historic Movement Data Directly

For subscribers the movement data recorded in the daily files in your account will reflect your account settings for that day. For example, if you have 9.00am as your benchmark comparison time, all the price movement figures in your CSV and XLSX files will reflect this. You will have full access to your historical data for the periods of time your subscription is active. 

This is of course fundamental to you understanding valid price movement and market movement noise probably bolstered by bookmaker and private trader activities. In essence, look for recurring patterns where winners and placed horses are shown against regular movement linearity. Also, of course, sudden price drops at various times of the day.
