What weapons, armour and accessory are worth selling in the trade market compared to the blacksmith?

My bank is getting full with weapons, armour and accessories I don't need anymore. Is there a comprehensive list of items that are worth putting on the trade market instead of just selling them to the blacksmith? Any tips would be helpful.

 

Best tip is to check the price in the trade market itself for any items you think might be worth something. If you sell it for just a little less than the lowest seller, you will normally sell it.

Here's a "what items are worth taking" list from the lootrunners discord:

it's rather outdated and only looks at high level loot, but it's better than what I would come up with on the spot.

If you want a generally accepted rule:
Aside from some special cases anything below lvl 80 won't be worth a lot.
Unless it has a good ID it isn't worth selling
