Is there a way to get higher leverage then when selling EWJ puts other than normal margin. I know SSF contracts are available, but the spread is nasty. Is there a SSF options equivalent or another market closely related. I was thinking Nikkea 225 futures options or index options, but I'm not sure of which one to trade, (SGX, OSE, Singapore vs Osaka, N225, mini vs regular contract) or which version to trade futures options or Index options based on options liquidity.
