Difference in value

@Dames There is always a difference between the buy & sell price, that’s the by default.
In your case, there’s no additional spread mark up. The chart price you’re seeing is the BUY (ASK) price. Once you buy a stock, we calculate your investment value by what you can sell them for so we use the SELL (BID) price - which isn’t visible on the chart. Unfortunately, there’s not one single universal price which you can trade on. There’s always a small difference between the best bid & ask price.
