early price database?

[HenryTD]

It seems that a huge amount of past data is available concerning horse races. The the trainers, the jockeys the going - all that kind of stuff in amazing detail (e.g. using proform). This is great for building and testing horse race prediction systems, but when it comes to historical odds, there is a dearth of information, especially with regard regular (non-exchange) bookmakers. It seems that the industry SP is all you can get. Does anyone know of a source of historic bookmaker prices at any times earlier than the race start time? I'd love to back-test what would happen if I placed my bets early in the morning. I did actually find one source but there was no information about rule4 reductions so the information was as good as useless.

Welcome to the PL @HenryTD

You have to ask yourself who would have such information - the bookmakers themselves

So why would they arm the punter with more ammo?

We keep a track on our tips prices, taking 3 checkpoints.

When we back them (6pm), in the morning (9am) and SP 

All I can say is that its slightly in favour of taking a price as early as possible, depending on how good you are at picking winners of course!

Good luck
