RuneScape:Grand Exchange Market Watch/Herb Index

Jump to navigation Jump to search

The Herb Index is made up of a weighted average of all of the grimy and clean herbs listed in the Market Watch, with the starting date of this average on 10 June 2009, at an index of 100. The overall rising and falling of herb prices is reflected in this index.

While specialised for just watching herb prices, it is set up and adjusted in a manner similar to the Common Trade Index, and the divisor may be adjusted to include new herbs added by Jagex (see the FAQ for more information).

As of today, this index is 525.12 Down.svg -4.47
