No.
Prices are falling except for ships, because the items required to build them decrease in prices. Just speculation.
Markets are less provided for the simple reason that the relist fee makes it impossible to list something over a year + . So you are stuck with 10 orders for the same items, and they all expire at the same time and people place the same for no reason … but they can’t just stop placing orders otherwise they don’t sell. So place less.
That’s why I made this post Replace relist fee with sleeping order
