This is equivalent to the example above - but `config-private.json` is specified as cli argument.
??? Note "config collision handling"
If the same configuration setting takes place in both `config.json` and `config-import.json`, then the parent configuration wins.
In the below case, `max_open_trades` would be 3 after the merging - as the reusable "import" configuration has this key overwritten.
``` json title="user_data/config.json"
{
"max_open_trades": 3,
"stake_currency": "USDT",
"add_config_files": [
"config-import.json"
]
}
```
``` json title="user_data/config-import.json"
{
"max_open_trades": 10,
"stake_amount": "unlimited",
}
```
Resulting combined configuration:
``` json title="Result"
{
"max_open_trades": 10,
"stake_currency": "USDT",
"stake_amount": "unlimited"
}
```
