Hi. I have the same question and I'm bit confused about this aspect to be honest.
I currently have a GBP Shares ISA (now fully liquidated). I am looking to start daytrading, solely with US stocks, however I would like, if possible, to avoid the 0.5% currency conversion fee as this equates to 1% per daytrade (buy/sell). Is this possible to do and still receive the zero commissons for US stocks?
Thanks.
