I'm trying to figure out the formula for calculating the UnsettledCash value at broker TDA.
I don't know whether this is documented somewhere, but I suspect it's not,
therefore I try to figure it out the hard way by making screenshots before and after the order,
and then analysing the changes and differences in all the account value numbers...
One would expect that UnsettledCash should be the proceeds from sales.
But it somehow does not sum up. In my CashAcct I made this test trade:
I opened 1 CashSecuredPut contract with Strike=3.50 and Premium=0.40,
but after the order got filled, the UnsettledCash value climbed from $0 to $389.34.
My questions: why so much has been declared as UnsettledCash, and how is it calculated?
Should that not be rather just only $40 per contract, ie. the Credit one receives?
Anybody know the formula for UnsettledCash calculation?
Update:
It seems broker uses the formula "UnsettledCash = (Strike + Premium) * Multiplier - Commission - Fees",
ie. (3.50 + 0.40) * 100 - 0.65 - 0.01 = 389.34.
But is this formula the correct formula at all? I have my doubts...
I of course have via a WebTicket also asked the support, but it takes some time. Maybe someone here is faster.
