问题如下：
If the options (concerning delivery times and what can be delivered) available to the party with a short position are increased, do you think the futures price increases or decreases? [Hint: An option always has a positive value to the holder of the option.]
解释：
The more options that the party with a short position has the more attractive the contract is to that party. They are therefore prepared to agree to a lower delivery price. Options available to the party with a short position therefore tend to lower the delivery price.
有个疑问，就是如果我作为卖放short，为啥我不想收到高的价格？而且选择lower price。我唯一能解释通的就是，因为我想把我的lowest 货品先卖出去？可是，这个行为在市场上成立么？？我要是short我肯定希望先赚到最高的利润呀！？不是很懂国外的逻辑
