This metric shows the 30-day change in the regional price set during US working hours, i.e. between 8am and 8pm Eastern Time (13:00-01:00 UTC), respectively Eastern Daylight Time (12:00-0:00 UTC).

Regional prices are constructed in a two-step process: First, price movements are assigned to regions based on working hours in the US, Europe, and Asia. Regional prices are then determined by calculating the cumulative sum of the price changes over time for each region.

This is the Point-in-Time (PiT) variant of US Month-over-Month Price Change. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
