Maybe I am doing this wrong, but it does not give me margin for the position, it gives me margin impact on the account of a position, which means I have to go find my account balance and then subtract the impact amount to get how much margin I am using for a certain position. Am I wrong? And I have to create a line on my page to get it, right? And then delete it?
And what if it is a combo position like a covered call, how do I see how much margin is being used on that particular position.
Maybe I am being fussy, but it seems that with all the TWS options having a column that shows margin used for each line or lines highlighted would be very useful. Is this the sort of thing I have to labor with a programmer and the API to get?
