Hello, I was looking for a European style index alternative to SPX, and the 'options' seem to be XSP, DJX, and MNX. I searched through the ET forums, there was some interest in these in 2005 and 2006 but since then there has been very little interest in them, and marginal mentions of these products on Google outside of CBOE literature. Nonetheless I'd still like a cash settled option. Has anyone traded these recently? XSP OI is small, MNX slightly better, and DJX has the largest OI. Very little volume as of 10:42am. Because these are electronic does that 'guarantee' fills or is that just an exaggeration? Even if hitting the bid/ask? Reading the thread SPX Credit Spread Trader there used to be some ET members trading these, but again that was 5 years ago. I feel like I'd be stepping back in time to a relic of the past if I traded these. That said, European cash settled is my only preference for these outside of trading the liquid options like ES or SPY. Any feedback is welcome.
