Similarly, an increase in open interest along with a decrease in price confirms a downward trend. An increase or decrease in prices while open interest remains flat or declining may indicate a possible trend reversal.

The Marshall-Edgeworth index, credited to Marshall (1887) and Edgeworth (1925), [11] is a weighted relative of current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting. It is considered a pseudo-superlative formula and is symmetric. [12]
Liquified Natural Gas (LNG) contracts are legal agreements for the sale and purchase of LNG between sellers and buyers. [9] LNG is an energy commodity, like crude oil, allowing for a price relationship between the two. [10] LNG contract pricing has been based on the JCC index since the 1970s. [11]
Price indices are represented as index numbers, number values that indicate relative change but not absolute values (i.e. one price index value can be compared to another or a base, but the number alone has no meaning). Price indices generally select a base year and make that index value equal to 100.
A cost index is the ratio of the actual price in a time period compared to that in a selected base period (a defined point in time or the average price in a certain year), multiplied by 100. Raw materials, products and energy prices, labor and construction costs change at different rates, and plant construction cost indexes are actually a ...
It allows investors to track the price, risk and volatility of the Canadian commodity. [7] The CCI provides a fixed price reference for Canadian crude oil and provides an accessible and transparent index to serve as a benchmark to build investable products upon, and could ultimately increase its demand to global markets.
The Platts assessment process determines the value of physical commodities 15–30 days forward for many oil products loading in Singapore. [1]MOPS is an acronym that stands for the Mean of Platts Singapore, and typically refers to any contract mechanism that derives its value by referencing the average of a set of Singapore-based oil price assessments published by Platts.
There is a substantial body of economic analysis concerning the construction of index numbers, desirable properties of index numbers and the relationship between index numbers and economic theory.
