Inspect daily product history

Open any product above or enter an ASIN to compare price, BSR and review observations over time.

How these observations work
Observed

Prices, positions, ratings, reviews, BSR and public bought signals when Amazon renders them.

Explainable

Demand Index lists its inputs and returns no score when signal coverage is insufficient.

Auditable

Visible demand signals are lower bounds, not invented sales estimates. Every point keeps its observation date.
