The players in the indices are weighted equal(independent of their price).

These indices can be used as a measure on how the player prices develop over time.

The last tab on each index graph will give you the option to see which players are included in the index.

The Top up/down on the bottom of the index page will show the biggest players fluctuation that are included in the specific index. The fluctuation is calculated from the price taken at the start of the day (UTC time).

The Market Momentum will show the "mood" of the market - if it's negative, neutral or positive. A value of 50 is neutral. The closer the value is to 0, the more negative the market is (maybe overwhelmed by new players from packs). And vice versa, the closer the market is to 100, the more positive the market is (could be lack of packs or a recovery from big packs).
