Matchbook does not like having thinly traded markets. I seem to recall they had them last year for the 'tv games', and there wasn't much action, but I could be hallucinating. I wrote them in November after they offered only a spread and moneyline but no total on the Indy/Atlanta Thursday night game. This is their reply:
Thank you for contacting us and for your interest in live wagering.
Your point is one we hear frequently, that it doesn't "cost" us anything to offer all markets for live wagering. The long-standing reply from the Matchbook end is that there IS a cost to empty/unsupported markets: namely, that it feeds the notion among North American bettors that the exchange concept is a good one, but that liquidity is weak. There's also a cost on the client side (i.e, the search costs associated with checking a market only to find it illiquid). On balance, we assess both those costs as non-trivial.
Alone among the US-facing exchanges, we've never posted markets unless we've got some arrangement in place to ensure a minimal level of liquidity/market support. On balance, it's a policy that's worked out well to our minds -- and we generally find clients understanding, once the rationale is explained to them. It's a policy we're constantly revisiting, especially as Matchbook liquidity continues to grow every month.
We apologize for any inconvenience caused, however if you have any questions, please feel free to contact us by email, live chat (via our Contact Us page), or telephone.
Kind Regards
