I'm currently waiting to transfer my stock&shares ISA to IG.
Do I have to wait for it to complete to invest here? I opened other ISA in June 2020. Haven't fully used the £20,000 limit. So can I invest the remainder while I wait or do I have to wait for transfer to complete? As maybe it'll count as opening two ISAs in a tax year??
When do they start? Currently have 0 balance and waiting for transfer. Would I be charged?
When does each quarter start? is it Jan-Marc, Apr-June, etc? or varies depending on when i start/transfer complete.
