Interesting, I've been through the list of trade-able instruments on their site.  Without counting them, I'd recon that about 3/4 of my most recent positions would be available there.  Seem a bit odd that they only have some, not all, of the SPDR US Sector ETFs.

The ETFs look limited currently, mostly only ones listed on LSE. But I'm most interested in being able to trade US stocks in an ISA properly i.e. during US market hours without having to use a CDI of the stock that only trades during UK market hours (like I have to in my SIPP account). Also, the zero commission thing will help too if they don't add too much to the spread to make up for it. But I will see how it goes on that front. But trialling it with a small account to begin with, as think you can only test something properly with real money to see how it compares.

Degiro would have been my preference if they had an ISA, as you can trade anything and has low fees, margin options, multiple currencies etc. But they still don't offer an ISA currently.
