Paul,
Your original question is not 100% clear but basically you can ONLY deposit £20,000 into a stocks & shares ISA in any 1 financial year.
You don't have to pay in £20,000 in 1 hit, you can pay it in over the course of the financial year but £20,000 is the maximum you can deposit.
You can trade to your hearts content BUT if you withdraw money from that ISA you cannot pay it back in until the following financial year when you will get another £20,000 allowance.
You could (if you're lucky) trade (buy & sell) that original deposit within the ISA into say £1,000,000 or more and it would be protected from any capital gains tax.
ALL dividend payments received on shares held within an ISA would also be free from tax.
Hope this helps.
