Is this an FX issue or a mathematical miscalculation?
Bit difficult to see in your screenshot. At history you can see the price and FX at the moment of purchase. Compare it to FX now.
Apparently the current price is 88.040000. I donβt see how that figure came to be. @David @George. Can you please advise?
Your return can be a negative value even though the sell price is higher than your avg price when the instrument currency (USD) has depreciated in regard to your account currency (GBP) for the period of owning the shares.
