Everything you need to know about Pokemon GO Trading

1. How do you trade Pokemon with another trainer?

Both you and the person you want to trade with are level 10 and higher.
In order to make any trade: you will need to be friends. You will need to ask for other Trainer Code and use it to send them a Friend request. Once he/she accepts, you’re friends.
When you want to trade: Meet up with the Friend you want to trade with. Both of you have to be within 100 meters of each other for trading to become available.
Finally, enter the trading mode, select the Pokemon that you want to trade, and confirm the trade

Special Trading is a set of trading rules which applies when trading particular types of Pokemon. The following Pokemon types are considered special trades:
- Legendary Pokemon, or some Mythical Pokemon that allow trading (e.g. Meltan, Melmetal)
- Shiny Pokémon
- Un-owned Pokemon (Pokémon not already in your/your friend’s Pokédex) or forms of Pokemon (like Unown, costumed Pikachu, Castform, Charmander, etc.)
You can only do one special trade each day.
