FuturesBetting/TwoWayFutures are the only option for API & automation via spreadbet. You wont find it anywhere else. The only reason you can do it via these guys is because they are "direct access" SB. Anywhere else is just making their own market, and if they were to offer an API it would open them up to arb against the underlying, or arb between SB firms. they might as well give away free cash like WorldSpreads were with their slow quotes.
