As of today, the 25th of December 2020, we will be increasing the minimum value order amount for a slice within a pie to £1. This means that the minimum investment amount for your pie will be adjusted also. Dividend Reinvesting (DRIP) will be triggered once the amount in your pie cash surpasses the pie's threshold.
Depending on the number of slices and percentage allocation, you can calculate your pie's minimum investment amount and dividend reinvestment threshold (DRIP). You can find more information regarding the threshold here.
