My only regret is that I did not do the trade a couple of days ago. GVC came out with a trading statement and the price shot up by 3%. I would have preferred to have that profit in my ISA than in my SIPP. Even there the BED and ISA deal helped because I was able to do the trade close to the sell price instead of the buy price and managed to shift some of the profit into the ISA that way.
In order to purchase into my ISA I sold off poorer performing US and HK shares (DRAD LEE 1001 635 287). To do this I had to pay the 2% exchange rate fee. You will remember this is the whole reason why I shifted my only remaining UK SIPP share into my ISA: to avoid paying these outrageous costs each time I trade.
