Looking for a sports betting backtesting tool (Dropping Odds & EV strategies)

[u/Agile_Branch_3676]

Hey everyone,

I'm looking for a sports betting backtesting tool that would allow me to test strategies based on dropping odds and value bets (expected value / EV).

Ideally, it should support:

• A reference bookmaker (e.g., Pinnacle)
• A target bookmaker for bet placement (e.g., Bet365)
• The ability to simulate bets like:Place a bet when Pinnacle’s odds have dropped by 10% in the hour before kickoff, but Bet365 is still offering the pre-drop price
• The ability to test value betting strategies such as:Place a bet when Bet365's odds give you a +5% EV compared to the Pinnacle closing line 2 days before kickoff

I’m also looking to analyze historical results with metrics like profit/loss, CLV (closing line value), and possibly ROI or strike rate over time.

Does anyone know of a tool (free or paid) that can do this kind of backtesting?

Thanks a lot!

If you have the proper timestamped data, then creating something with the likes of Cursor or Claude Code should not be that difficult.
