Is it possible to move pies between accounts?
You can copy the Pie from your Invest account to your ISA or vice versa, as long as it’s public. To do so, open your Pie and click the “Save” icon.
Then open your second account → Pie Library → Pies → Saved, and there you’ll find a copy of the Pie.
Just to let you know, some stocks may not be eligible to be held in an ISA account if they don’t cover the criteria.
