同学你好，你这样算不行。
对于FRA结算，settlement是发生在FRA到期的时刻。在2时刻，就是FRA到期的时候，求交割，我们就用（FRA-libor）乘以本金再折现。相当于我们签订了FRA，我们收到FRA乘以本金这么多利息，不签订FRA我们收到libor乘以本金这么多利息，那么签订FRA交割的金额就是两者相减再折现（就相当于算签订FRA带给我们的好处）。原版书也给出了计算公式。Settlement amount at h for receive-floating: NA{[Lh(m)−FRA(0,h,m)]tm}/[1+Dh(m)tm]
Settlement amount at h for receive-fixed: NA{[FRA(0,h,m)−Lh(m)]tm}/[1+Dh(m)tm]。
