freqtrade new-hyperopt --userdir ~/.freqtrade/ --hyperopt AwesomeHyperopt
```
## List Strategies
Use the `list-strategies` subcommand to see all strategies in one particular directory.
```
freqtrade list-strategies --help
usage: freqtrade list-strategies [-h] [-v] [--logfile FILE] [-V] [-c PATH] [-d PATH] [--userdir PATH] [--strategy-path PATH] [-1]
optional arguments:
-h, --help show this help message and exit
--strategy-path PATH Specify additional strategy lookup path.
-1, --one-column Print output in one column.
Common arguments:
-v, --verbose Verbose mode (-vv for more, -vvv to get all messages).
--logfile FILE Log to the file specified. Special values are: 'syslog', 'journald'. See the documentation for more details.
-V, --version show program's version number and exit
-c PATH, --config PATH
Specify configuration file (default: `config.json`). Multiple --config options may be used. Can be set to `-`
to read config from stdin.
-d PATH, --datadir PATH
Path to directory with historical backtesting data.
--userdir PATH, --user-data-dir PATH
Path to userdata directory.
```
!!! Warning
Using this command will try to load all python files from a directory. This can be a security risk if untrusted files reside in this directory, since all module-level code is executed.
Example: search default strategy directory within userdir
``` bash
freqtrade list-strategies --userdir ~/.freqtrade/
```
Example: search dedicated strategy path
``` bash
freqtrade list-strategies --strategy-path ~/.freqtrade/strategies/
```
## List Exchanges
Use the `list-exchanges` subcommand to see the exchanges available for the bot.
