So basically, I can make a trade that buys and sells keys at 5 ref and leave the trade at that, then there's no problem? The only thing that was mentioned was the fact that I stated I didn't agree with the current price. If I take that text away, it's still the same trade, still the same idea, and can have the same affect (evidence that the price is possible and therefore "price manipulation"). But it then complies with a rule that I've still yet to see.

As for buying low and selling high, no, that wasn't my intention. As I last commented on that trade, I may not be a well known person, and I may not have a huge reputation throughout the community, but the record I have is clean and I hope to be developer for a portion of a raffling once I get more coding skills under my belt. I have a self-reputation that I take seriously, whether anyone here, besides close friends, actually understands that or not I can't help. But it does stand that record has been clean for the whole of my time here and my intentions have never deviated from that path.

This goes against no rules, and is simply a buying and selling of keys, just like every other key sale going on. I've seen many trades still live that sell/buy for this exact, if not a lower, price. And this whole website is about price manipulation; trying to sell things for more and buy things for less. Personally, just don't see price manipulation as a good reason for closing trades. If someone could define it for me (because I haven't been able to find a definition by this site/group) that'd be much appreciated.
