Unlike their cousin the Volcker Rule, neither Liikanen nor the UK approach attempts to draw a line between types of trading. Judging whether trading is proprietary might not quite require “windows into men’s souls” (which in another context Queen Elizabeth I wisely avoided), but America’s experience shows that it is difficult all the same.
这本身并没有什么区别。毕竟，设置篱笆将鹿和狮子隔开与设置篱笆将狮子和鹿分离是完全一样的。与它们的表兄弟——沃克尔规则（Volcker Rule）不同，利卡宁和英国方案都不准备给交易类型划线。鉴定交易是否属于自营也许并不要求“心灵的窗户”（这又是伊丽莎白一世巧妙地避免的另一种环境），但美国经验表明这同样困难。
