 我还是觉得　应该是２个单位的Ｓｔｒａｄｄｌｅ　以前好像看到过这样的题目

Ｉｍｐ. VWAP or Crossing?
第一个　Ｉｍｐ，　因为是　long term and large spread　首要目的是减少交易成本　所以是imp.
第二个　ＶＷＡＰ，　因为　urgent, informative motivated, 所以要ＶＷＡＰ　基本可以保证当天内成交。
Ｎｏｔｅｓ里有一个相似的题目，答案是一样的

 if the risk free yield increases, which leads to reduction of bond price, such risk can be eliminated by using futures.
if risk free yield decreases, such case should not be considered.
