I have recently sold my first CSPs in an IBKR cash account.
At the point of sale, an amount of the buying power/available liquidity is locked up in maintenance margin. The amount is the funding needed in case the shares get assigned. From what I have gathered this balance doesn’t earn any interest, despite it just sitting there until potentially required.
Is there a more optimal way around it? Would I need to enable naked option selling on the account and just monitor the liquidity myself?
Thanks!
