So I tried various ways of entering the transaction but it continues to ask for more funds in margin to close the transaction. I think some posters have commented that closing position would release margin. The problem is here I cannot even close the position without putting even MORE margin. This is counter-intuitive so I wondered if I was doing something terribly wrong. (I will contact my broker next week).
Lower the number of Buy to close AAPL 525.00 put contracts from 4 to 2. Then Sell to close 2 contracts AAPL 522.50 put contracts. Once those trades are completed close the remaining puts.
That should be faster than contacting the broker.
Any other IC adjustment straetgies one can think of?.
No such thing as "IC adjustment strategies". The IC either makes money or loses money, then you are on to the next trade.
