Anyone know of any alternative marketplaces/exchanges to electronically trade options for CME index futures afterhours?. ES/NQ/YM some FX can be denominated in $'s or euros. Level II DOM for CME Options appears to only reflect the Market Makers designated by CME. CME does not provide complete DOM for options and the market maker's spreads are not competitive outside of RTH's.
How an "alternative" exchange to the CME trade "CME" index and currency products? In short the answer is no. I've traded ES options a few times at night and there was some liquidity. You may need to be flexible in terms of strikes but usually somewhere in the book there's a retail order you can trade against without giving up a huge edge. The other markets you mention: forget about it.
