请教: 哪里可以找到 HEAVY OIL 重油的QUOTE, FUTURE的TICKER也行. (LIGHT CRUDE 的QUOTE 很多,但没找到重油的).
科普读物:
Crude oil comes in a variety of blends classified according to density and sulfur content. Light, medium and heavy refer to the density of oil. The terms sour and sweet are based on sulfur content; crude containing more than 0.5% sulfur is considered sour.
The more valuable grades, such as WTI, are light and sweet. Conversely, heavier and more sour grades such as Chinese Daquing大庆 are less expensive. |
