Value on shares

could anyone answer a question for me please.
I have purchased shares, and the value is more than what I have bought for, but no change in the price! Is this because of the exchange rate £-$

@Dames Yes, that must be the case because the app displays the current market value of your investment in the currency of your account.

This is also why sometimes you can see the value of your investments change even though the stock market is closed.
