## Storing information (Persistent)
Storing information can also be performed in a persistent manner. Freqtrade allows storing/retrieving user custom information associated with a specific trade.
Using a trade object handle information can be stored using `trade_obj.set_kval(key='my_key', value=my_value)` and retrieved using `trade_obj.get_kvals(key='my_key')`.
Using a trade object handle information can be stored using `trade_obj.set_custom_data(key='my_key', value=my_value)` and retrieved using `trade_obj.get_custom_data(key='my_key')`.
Each data entry is associated with a trade and a user supplied key (of type `string`). This means that this can only be used in callbacks that also provide a trade object handle.
For the data to be able to be stored within the database it must be serialized. This is done by converting it to a JSON formatted string.
