Understanding Price Indices
Last updated: March 19, 2026
A Price Index is a dataset that defines the value of a price at regular time intervals across a specified time range. Each point on the index represents the price applicable for a particular interval, allowing systems to model, forecast, or apply prices that fluctuate over time.
Rather than representing a single static price, a price index captures temporal variation, enabling accurate representation of markets where prices change frequently due to supply, demand, or market conditions.
A Price Index can be historical, or a forward forecast.
Price Indices are referenced in Rate Sets.
Factor Price Indices can support any interval definition e.g. 5m, 15m, 30m etc.
