AutoReinvest dividends options in Pies is awesome, but I believe it could be improved. My suggestion is to allow the user who activates this feature to set a percentage of the money earned through dividends that he wants to reinvest in the pie.
For instance, let’s say you are earning 100 euros in dividends and only want to reinvest 30 euros of those and keep the other 70 euros to spend somewhere else, or the other way around. You would be in charge of what happens. For this particular case, you would set the reinvestment percentage to 30% in the pie, and Trading 212 would do the math for you.
