“The entity cannot be travelling and must be in a system, or on the ground in a city or on a planet, or inside a market. If you try to sell raw materials, then the pile can be instead located inside a NPC-owned facility.”
I believe this is what you are referring to Syn. It does rather give the impression that items are deposited/made available prior to selling. I 'assumed' the conditions were linked to the goods available.
Is there a more indepth posting about the market you could link me to please.
That only applies to stuff that people actually sell to the market; this is very, very rarely the case because there are no profits in selling to the NPC market over a person. So you get almost entirely death assets which can be spread all over.
“I believe this is what you are referring to Syn.”
No, I'm referring to this, at the end of the introduction: It is also important to note that the goods available for sale on the market are not always inside NPC-owned facilities. Therefore, it can happen that you may have to contact the owner (character or faction) of the facility containing your purchased goods in order for you to settle a way to retrieve them.
The introduction seems vague, hence i missed your reference. When you now consider that the market place is mostly accessed via Spacestations etc, faction owned, that statement is theoretically true every purchase. So I didn't 'get' anything from it.
The Conditions were presumed to apply to all applicants to the market.
That all said, I can only offer the view of someone who didn't understand.
If you have a suggestion for the phrasing that would make it more clear to you from the perspective of someone newly using the feature (and this applies to any rules page), please feel free to post in the rules update forum so maybe we can get some of the phrasing clarified for people in your shoes in the future.
