Currently, the stat you get on the homepage of the app e.g. “£322, Up By £65 since you began investing” is pretty useless.
It includes top-ups as an improvement in your portfolios performance and doesn’t actually tell you anything useful - in my opinion.
It would be better if we could set custom date ranges e.g. showing how much your stocks have improved over the last week.
Of course, you can choose 1D, 7D, 1M, 1Y or MAX but these do not change the stat at the top, and this also resets to 1M everytime you reopen the app.
