How the index is calculated
- Choose up to five references with at least 12 observed sale dates, ordered by coverage and then reference. The basket stays fixed across every date in that published snapshot.
- For each date, calculate the median of daily medians over the preceding seven days. Every basket member needs at least three observed dates and five sales in that window. No missing sale price is estimated or carried forward.
- Set each reference’s seven-day value to 100 on the first qualified date. Average their price ratios with equal weights. That is the index.
Brand and model pages use the same method within their own groups. An index appears only when at least two qualified dates exist. As catalog coverage grows, a new snapshot can select a different basket; compare the basket and base date alongside the line.
