I skimmed the threads looking for a clarification on the use of Trade [$] powers and didn't see one which directly answered my question, but in this thread Tom Lehman says:

Just trying to be explicit. Some playtesters had interpreted the "this world" trade power to imply that other trade powers (relevant to the good kind being traded) would not apply in addition to the "this world" trade power, which was incorrect.
As I read this, when you choose "Consume: Trade" and one good is traded, can you apply all applicable trade abilities which are on worlds or developments in your tableau?
For example, I have a good on the Pirate World. I trade it and get the +3 cards from the power on the Pirate World. Would I also be able to apply the draw +1 for selling any good power from Old Earth and the draw +2 cards for selling a Novelty (blue) good from Spice World, for a total of 8 cards (2 + 3 + 1 + 2)?
