We're http://www.Oddsfutures.com and we hope to change the exchange trading and betting ecosytem for the bettor.

We're basically a derivatives exchange for horse racing odds prices. We provide an alternative and hopefully a remedy to the problem of adverse selection for exchange betting traders.
Our API is available for free for anyone that wants to have a play https://www.oddsfutures.com/ofapi_v1/
We allow price traders to trade prices rather than having to trade bets. We are bridging the gap between true market trading and sports.
Yes liquidity isn't great but it is growing, but as we charge on matched amount rather than profit tax it should grow quickly. Fees start as low as 0.1% up to a max of 2%.
I look forward to interacting with Betangel members to get advice and feedback.
Thank you!
