nope, you open up the market window - you see a list of categories, which are further divided by subcategories, etc.

until you click on each individual possible item, you wont see if its offered by other player or not.
it needs a few other clicks to find out if the same item is somewhere else, (then your current location), on sale or in demand.

the alphabetical sorting within the tree, together with the random, meaningless, naming of the tiered items, its hardly possible to get an overview without clicking through every single item manually.

last but not least, there are "trading" extensions - all they do is enabling, none of them offers "trading" features like remote access, statistics or market window improvements...
