And when a Wall Street trader comes into work in the morning, she does not write a listing for every financial derivative she wants to sell today and then post that listing on multiple websites and wait for potential buyers to get in touch and start negotiating the terms on which she might trade.
当华尔街交易员早上上班时， 她不会为每个她今天想要卖掉金融衍生产品去列表 然后把这个表发到多个网站上 等待潜在买家来联系 好开始谈判她可能交易的条款。
