这道题时间点判断居然是t=0时刻求value？！确定题目没问题吗？
NO.PZ201702190300000104 老师好 这道题我没看出来“current quoteprice”对应的current时间点就是t=0的时间点，从哪里可以看出来呀？谢谢老师

NO.PZ201702190300000104 ¥139,913. ¥239,963. C is correct. The current no-arbitrage priof the forwarcontrais Ft(¥/$,T) = St(¥/$)FV¥,t,T(1)/FV$,t,T(1) Ft(¥/$,T) = ¥112.00(1 - 0.002)0.25/(1 + 0.003)0.25 = ¥111.8602 Therefore, the value of Troubaur’s position in the ¥/$ forwarcontract, on a per llbasis, is Vt(T) = PV¥,t,T[F0(¥/$,T) - Ft(¥/$,T)] =(112.10 - 111.8602)/(1 - 0.002)025 = ¥0.239963 per $1 Troubaur’s position is a short position of $1,000,000, so the short position ha positive value of (¥0.239963/$) x $1,000,000 = ¥239,963 because the forwarrate hfallen sinthe contrainitiation.可以用t时刻的forwarprice折现到current 时间点与当前spot price做差吗。稍微差了179块钱，不十分准确.
NO.PZ201702190300000104 带入讲义中currenforwar公式， 之前有人提问中回答的画图法，ST=112.1, FP=112 想请问下题目中 contrainitiation, the forwarrate w¥112.10 per $1. 我觉得这个forwarrate不应该是FP吗？ The forwarcontraexpires in three months. The current spot exchange rate is ¥112.00 per $1，这个应该是ST。为什么答案是反的呢？
NO.PZ201702190300000104 一直搞不明白到底哪个货币在期末支出。为什么long forwarfpA/B，期末支出FPa呢
