But if the OP can live with higher commissions etc., you can combine Saxo and IB so that the CFD universe becomes larger. However, it will not be complete and it will not include IPOs.
When I mentioned IPOs it was just example. I tried to find many stocks as CFDs on IB and they said it is not liquid enough to be a CFD ! it seems they have limitations about CFDs (liquidity , price , .. )
yes, they sometimes hedge your trade on the real market and need liquidity to do that at the right price. but I don't see a reason why you need CFD unless for the high leverage available, right?
they don't have short selling rules! this means you can short sell even if the stock is below 10% ... this is really helpful in day trading
