MLSs are not required to track or report price change information other than the most recent increase or decrease in the price of current listings. If such information (either with respect to a current listing or to prior listings of that property) is tracked by an MLS and made available to participants and subscribers, neither it nor any information from which it may be determined shall be classified as confidential nor may participants be prohibited from making such information available to clients and customers pursuant to the same rules governing dissemination of other non-confidential data fields. Classification as non-confidential permits inclusion of such information in advertisements, including IDX display, of other participants' listings as a matter of local option.
