Fix spread broker with regular market hours

hey all,

i’m looking for a broker with fixed spread (as low as possible of course) AND that opereates during the full market hours. what i mean by this is, that for example etoro (yes, back in the days started as a newbie too) has fixed spreads, but! the market opened one or two hours late after the weekend and closed one hour or so early on fridays.

so the broker i’m looking for should have fixed low spread and should openat 10gmt on sundays (i think that’s the standard open after the weekend, correct me if i’m wrong) are the two main important things as i want to test something that requires this two features.

alternatively, a broker with no fixed spread but also low spread right on the open after the weekend would be equally good.

thanks in advance
