I posted this Friday and again yesterday but if you did miss it, it's the US Independence Day holiday today, July 4.
Markets will be closed:
- stock exchanges
- bonds
- FX (FX never entirely closes but it'll be super-thin, negligible, liquidity)
As for Globex, I posted its hours:
found at AMP Futures, which I know nothing about except their holiday hours summary is very helpful.
Of course, you can find full details at the Chicago Merc's website:
