RE: read the RNS and future outlook again and again28 Nov 2020 21:56
Yes there is.
USA markets for example open 1 hour before market open, 8:30, the hours before that is futures trading, ie: you are trading the future, not set in stone, until it opens.
If you see a HUGE sell go through within the after hours trading slot watch the stock open down the next day as the MM's price it in.
Not sure where you got that info from?
