How do I trade part?

Because before I ragequit at the tedium and my inability to get any good parts after hours of grinding, only for the bots I pumped into tens of thousands of UC to summarily be raep raep raped by macross missile massacres from FatArts the likes of which I don't know how to break the game with using only untuned UC shop parts, well, I'm just double checking what I heard about frustration being the only option before I go back to SDGO which, when I played it, never required one to spend real money to not get slaughtered like the cannon fodder most UC players in this game would be if, you know, it still had any of those. But considering the population is UNDER ONE THOUSAAAAAAAND, well, the cannon fodder must have been owned into extinction months ago, if not last year. As fun as making a Seraph run with its booster between its legs was with a bot that cost infinitely less, it's just not enough to make up for the lack of a trade system unless in fact there is one I haven't heard about.

Also: GAGAGA GAGAGA GUNDAMU! GAGAGA GAGAGAGA GUNDAMU! Because it's a dick move to not allow UC players to buy BRD's GarFighBot, the most awesome robot to ever exist in the game for painfully, excruciatingly, infuriatingly obvious reasons. Needs moar Bureikion Suramma.
