A Trade Pool is the group of Pokemon available to be WonderTrade'd for. Trade Pools have a certain number of Pokemon. Everytime a player "WonderTrades" with that pool, they get a random Pokemon from the pool, and the Pokemon they traded is placed in the pool.
Trade Pools are saved in the
/config/WonderTrade/TradePools
directory. While you can edit a Trade Pool's setting there, and then reload the config (/wondertrade reload), WonderTrade is designed for GUI editing of settings instead.
You should watch the demo video in WonderTradeto see the GUI settings in action.
Defining a Seed Pool with a random range instead of set level
You can use the format:
[minlevel-maxlevel]
To get a random level when generating the pool. For instance, instead of having
random lvl=10
As your only seed property, you could have:
random lvl=[5-20]
Which would then generate x amount of Pokemon with levels between 5 and 20.
This can be used anywhere numbers are accepted in Pokemon Properties, for instance with IVs/EVs.
