For those who rely on daily charts...

What do you envisage happening when the trading clock turns 24/7?

 

... it already is. I use daily charts "outside trading hours".

Not that big a deal.

 

look at the fixing times and standard expiration times.

 

Brokers won't go 7, it'll be 24/5 same as forex which runs active for the most part European open thru US close.
