How do you then explain the case that unsettledCash is 0 when ShortSelling a Call?I'm not convinced they made an error.
In this context, unsettled cash may not mean cash that you received from selling something. It may simply refer to cash that is on hold, and unavailable for withdrawal or trading, because it has to be there in case your short put is assigned. It's not cash flowing into your account. It's cash that was already there, but not it is unsettled until the short put is closed.
As said the broker calcs it only when a ShortPut trade gets opened, but not for ShortCall trades.
Can you think of any logic in this?
