I’m new to the platform and am puzzled why there’s a small reduction in the amount I purchase when I buy the VUAG ETF. I purchased £35 and got £34.80’s worth. I joined InvestEngine as they seemed low fee. The only thing I can think of is that it’s due to a conversion fee as I deposit GBP and the ETF is USD. Is this the reason or is it something else? Thanks in advance.
