I'm referring to long bond positions (whether be it treasuries or corporate bonds). I don't think it does because frequently, when I sell a position the value that it was market before (lets say +$521) turns into something bigger (lets say +$745). The difference is the accrued interest that the buyer of the bond paid to you when you sold. Depending on how long you held the positon, that interest can add up (up to the date where the coupon is paid, in that date the accrued interest will reset).
I understand there is a tab that says accrued interest but I do not think that includes accrued interest from long bond positions.
