Hi,
If you view a stock on Freetrade, and the price is lower than the open price, the graph is red (understandable). In reverse, if the price is higher - the graph is green.
This makes sense, however if you view the graph on your portfolio, the graph is always green - even if you are at a loss.
As painful as it looks, I think the portfolio graph should be red if you are at a loss for the day, week, month and max view.
This is in keeping with the stock graph view and just makes more sense for the user.
