What good trades have you pulled off, and what bad ones? Trading with alts doesn't count.
Good trades for me;
Groudon for shiny Wingull. Traded out a low IV Groudon i didn't need. Given my horrible luck for catching wild shinys this is good for me.
Shiny ho-oh for shiny Articuno. After skipping Articuno day i traded a ho-oh to get one, and it turned out lucky. Not great IV's but still happy with that.
Shiny Moltres for Shiny Kagikarp. I've seen almost 2000 karps and none were shiny. I'm probably never going to find a wild one so needed this trade.
Bad trades;
Shiny Zapdos for Shiny Pikachu. Missed pikachu day so used up a shiny Zap for one. Serves me right for missing community day.
Rhydon for Rhydon. They went lucky, mine was in the 70's, the other persons in the 90's. Probably the worst trade i've made.
Lucky Squirtle. I have a lucky Squirtle. i don't know what i traded this for but it's a waste of a guaranteed lucky.
Shiny Jolteon for Shiny Vaporeon. Did this one purely as a favor for someone else, i never needed shiny vaporeon at this time. my altruism cost me 80,000 stardust. At least it didn't go lucky.
