Trading

Trading is a gameplay feature in Pokémon GO. It enables trainers to trade Pokémon who are in close proximity to one another.

Trading
Trading Pokémon can be done between two players that are in close distance from each other in real life. There are two sorts of trades: normal and special. All trades require both Trainers to use Stardust in order to complete the trade of any Pokémon. For trades in which players are swapping Pokémon already found within their Pokédexes, only a minimal amount of Stardust is required. This allows Trainers to freely trade most Pokémon that they encounter within reasonable limits, as Stardust is an important resource. Trading is special, and although several mechanics are in place to ensure that Trainers don’t take unfair advantage of it, there are also plenty of rewards to make these mechanics feel unique and personal.

Process
The stats of the Pokémon will change randomly within a range when traded. Before a Trainer completes a trade, they will see the range of CP and HP that the Pokémon could potentially have when the trade is complete.

There's a thoughtful calculation to deciding that range:


 * 1) Check Friend's Trainer level to confirm the Pokémon is not powered up past what would ordinarily be obtainable for someone at that level.
 * 2) Assign minimum stat values based on Friendship level, and that base increases the higher that level is.

In other words, as a Trainer's Friendship level increases with a friend, they will have a better chance of receiving a strong Pokémon when trading. A Pokémon that may not be great in battle may excel in battle once traded to a friend. In order to bar some Trainers from continually re-rolling a Pokémon's stats through trade, Pokémon cannot be traded back to the original Trainer. This feature promotes trading without giving a significant advantage to one Trainer over another. Trainers are currently limited to 100 trades per day.

Special trades
Special Trades can only be done once per day to limit the number of times a single Trainer can make Special Trades with all of their friends. Special Trading does become more accessible over time. As the Friendship level between two Trainers increases, the amount of Stardust needed to complete a Special Trade will significantly decrease.

New friends, making high-value Special Trades of Legendary Pokémon, Shiny Pokémon, and Pokémon not currently in a Trainer's Pokédex, will have to spend a large portion of their Stardust to prevent exploitation and the creation of a black market, which would devalue the hard work of Trainers who have managed to encounter and catch rare or powerful Pokémon.

Banned trades
The following Pokémon will not be allowed to trade.


 * Mythical
 * "Slashed" (Pokémon acquired by spoofing or botting)
 * Current Buddy Pokémon
 * Pokémon currently defending gyms
 * Feinted or unhealed
 * Unhatched eggs
