Tip

If you happen to start the bot and produce the error Oracle rate is not available, or ff the rate_oracle_source fails to show any price reference on your pair, you may change the oracle_source by running config rate_oracle_source and switch between Binance, Coingecko, Kucoin or Ascendex.

## How it works¶

If you need to view the rate oracle conversion after the balance, pnl, open_orders, trades, and status command, set it manually in the conf_client.yml.

Note

In past versions of Hummingbot (1.5.0 and below), the conf_client.yml file is named conf_global.yml

To set the parameters for rate_oracle_source, global_token.global_token_name and global_token.global_token_symbol, run the config command.

Refer to the example below:

Change the default setting in conf_client.yml to GBP (Great Britain Pound). The conversion will show up when you run balance command.

The conversion also shows up during the status command for the liquidity_mining strategy. Under the Miner section.

The conversion shows up when using the pnl command.

The conversion also shows up when running the trades command.

The conversion also works with the open_orders command.
