it will be great if you guys can consider something like the Big S&P and the emini S&P for the ETF futures contracts, so basically 2 contract size for the same product. To be honest, as much as i love SSF, i cant afford the 1000 mulitiplier. Also, IB doesnt seem to make markets for the 1000 multiplier SSF, so for example, even if we want to swap a 1000 shares position in USO to an EFP, we might have to pay a normal spread instead of the discounted IBEFP spread. Furthurmore, if someone can afford to trade a 1000 multiplier in the USO, they can just trade front month crude on globex directly instead of USO. Therefore, it is unlikely that a 1000 mulitiplier USO ETF would attract huge interest.
