### Metadata dict
### Metadata dictionary
The metadata-dict (available for `populate_buy_trend`, `populate_sell_trend`, `populate_indicators`) contains additional information.

The metadata dictionary (available for `populate_buy_trend`, `populate_sell_trend`, `populate_indicators`) contains additional information.
The Metadata-dict should not be modified and does not persist information across multiple calls.
Currently this is:
- Currency pair in the format `XRP/BTC`, which can be accessed using `metadata['pair']`.
- Timeframe used by the bot in its string form (`5m`, `1h`), which can be accessed as `metadata['timeframe']`.
The metadata dictionary should not be modified and does not persist information across multiple calls.
Instead, have a look at the section [Storing information](#Storing-information)
