I know CME e mini NQ and ES are open 24/5 The options for E mini NQ and ES are the trading hours the same as the parent symbol ??? ie 24/5? ( I mean globex and regular trading hours are they the same?)
You are somewhat mistaken... its not 24/5... its more like 23/6 (I think) Not 100% sure but globex options and eminis stop trading around 4:15 EST. Eminis start again shortly and so do options, but there is hardly any bid/ask on options and even then, its either rediculously low/high. Also Sundays they are open and can be traded... on e-minis you will see a slight volume.
For an example, bid/ask size in emini Dec 1500 call, after the close today - 17:24:27 x50 17:24:27 x50 17:24:24 50x50 17:24:24 50x50 17:24:24 x50 17:24:24 50x50 17:24:24 x50 17:24:24 50x50 17:23:06 50x50 17:23:06 x50 17:23:06 50x50 17:22:21 50x50 17:22:21 50x50 17:22:21 x50 17:22:21 50x50 17:22:17 50x50 17:22:03 50x50 17:22:03 x50 ... looks like a robot making a small market.
