Multivariate testing will find the truth but let’s take a guess at it…
I would rename “basic trade” to something like “end of day trade”, which more clearly explains the difference between an instant trade and what this is.
“Investment account” or “Standard account” might be slightly better signalling than “Basic”, once you have your gold/silver/bronze pricing segmentation in place. But given that you will launch with a single account type you could just call it “Account” for now!
I think there might be something confusing in the pricing grid at the moment where inside each price point the user is making secondary decisions that are different kinds of decision however are presented as if they’re the same kind of thing. One is instant vs end-of-day, a decision that the user will make every time they trade. The other is not-ISA vs ISA, a decision that they’ll make once I guess? Dunno, just wonder if particularly the basic account can be made to look simpler and an easier “ok i’ll do this” decision for users. Maybe you could present a third price point that was “Investment account plus an ISA, 3/month”, sitting in betw Investment account and alpha.
(And it’s obviously common freemium practice to add an expensive price point over on the right that you don’t actually intend to sell much of, but it helps increase purchases of the price point options in the middle by anchoring a high price. It’s an tactic but seems to actually work for many.)
