you have got 2 powerful filter systems to use when viewing the market.
filter on guild
your guild market should be your first port of call when looking for anything. trades in guild cost no forge points and your guild market should be free of spam trades *IF* you are in a decent guild which regulates fair trading. if not, take my advice and quit the guild, find a guild with a fair trade policy, they normally advertise this on their profile.
filter by offer / need
working out why you are looking at the market (apart from being bored or having nothing more interesting to look at... <cough>) is worth considering. are you buying or selling? who has what i want to buy? who has what i want to sell? are my bonus resources worth building a second factory for? are there lots of numpties selling what i'm producing or are they clamouring for my goods? it pays to watch the trends on your markets.
combine both filters, and you have tools to reduce the noise selectively. every login, i check the "Need" filters for each resource i'm producing with bonus. not that you should be even thinking of producing without a production resource bonus, that's what crazy noobs do, and kill themselves doing it. it maybe tedious to filter, look down the lists, select a new filter, rinse and repeat. but do you must, if as rich and totally loaded as Yoda you want to be, yes?
sometimes you can strike gold and find a frantic buyer who is offering a generous deal and hoping for a quick fill. it can be worth your while buying in from the rip-off merchants to make the deal and still come away with a profit. but think before you press the trade button. circular deals can be a great way to make a profit too, particularly if there is a surplus on your guild market and a demand on your neighbourhood or visaversa.
it is
always worth wading through the "junk" trades and the market spammers. always. one spammer on my list made the most stupid blunder and offered 20 for 10 deals instead of 10 for 20 deals on a two era split, with the eras inverted. i burned 10 forge points and made a freakin' killing!
i gave 20 limestone for 40 silk back times 10 deals, you do the maths*...
