The definition of each config parameters is in 
[misc.py](https://github.com/freqtrade/freqtrade/blob/develop/freqtrade/misc.py#L205).

### Understand minimal_roi
`minimal_roi` is a JSON object where the key is a duration
in minutes and the value is the minimum ROI in percent.
See the example below:
```
"minimal_roi": {
    "40": 0.0,    # Sell after 40 minutes if the profit is not negative
    "30": 0.01,   # Sell after 30 minutes if there is at least 1% profit
    "20": 0.02,   # Sell after 20 minutes if there is at least 2% profit
    "0":  0.04    # Sell immediately if there is at least 4% profit
},
```

Most of the strategy files already include the optimal `minimal_roi`
value. This parameter is optional. If you use it, it will take over the
`minimal_roi` value from the strategy file.

### Understand stoploss
`stoploss` is loss in percentage that should trigger a sale.
For example value `-0.10` will cause immediate sell if the
profit dips below -10% for a given trade. This parameter is optional.

Most of the strategy files already include the optimal `stoploss`
value. This parameter is optional. If you use it, it will take over the
`stoploss` value from the strategy file.

### Understand initial_state
`initial_state` is an optional field that defines the initial application state.
Possible values are `running` or `stopped`. (default=`running`)
If the value is `stopped` the bot has to be started with `/start` first.

### Understand ask_last_balance
`ask_last_balance` sets the bidding price. Value `0.0` will use `ask` price, `1.0` will
use the `last` price and values between those interpolate between ask and last
price. Using `ask` price will guarantee quick success in bid, but bot will also
end up paying more then would probably have been necessary.

### What values for exchange.name?
Freqtrade is based on [CCXT library](https://github.com/ccxt/ccxt) that supports 115 cryptocurrency
exchange markets and trading APIs. The complete up-to-date list can be found in the
[CCXT repo homepage](https://github.com/ccxt/ccxt/tree/master/python). However, the bot was tested
with the exchange listed below.

The bot was tested with the following exchanges:
- [Bittrex](https://bittrex.com/): "bittrex"
- [Binance](https://www.binance.com/): "binance"
- [HitBTC v2](https://hitbtc.com/): "hitbtc2"

Feel free to test other exchanges and submit your PR to improve the bot.

### What values for fiat_display_currency?
`fiat_display_currency` set the base currency to use for the conversion from coin to fiat in Telegram.
The valid values are: "AUD", "BRL", "CAD", "CHF", "CLP", "CNY", "CZK", "DKK", "EUR", "GBP", "HKD", "HUF", "IDR", "ILS", "INR", "JPY", "KRW", "MXN", "MYR", "NOK", "NZD", "PHP", "PKR", "PLN", "RUB", "SEK", "SGD", "THB", "TRY", "TWD", "ZAR", "USD".
In addition to central bank currencies, a range of cryto currencies are supported.
The valid values are: "BTC", "ETH", "XRP", "LTC", "BCH", "USDT".

## Switch to dry-run mode
We recommend starting the bot in dry-run mode to see how your bot will
behave and how is the performance of your strategy. In Dry-run mode the
bot does not engage your money. It only runs a live simulation without
creating trades.

### To switch your bot in Dry-run mode:
1. Edit your `config.json`  file
2. Switch dry-run to true
```json
"dry_run": true,
```

3. Remove your Exchange API key (change them by fake api credentials)
```json
"exchange": {
        "name": "bittrex",
        "key": "key",
        "secret": "secret",
        ...
}   
```

Once you will be happy with your bot performance, you can switch it to 
production mode.

## Switch to production mode
In production mode, the bot will engage your money. Be careful a wrong 
strategy can lose all your money. Be aware of what you are doing when 
you run it in production mode.

### To switch your bot in production mode:
1. Edit your `config.json`  file

2. Switch dry-run to false
```json
"dry_run": false,
```

3. Insert your Exchange API key (change them by fake api keys)
```json
"exchange": {
        "name": "bittrex",
        "key": "af8ddd35195e9dc500b9a6f799f6f5c93d89193b",
        "secret": "08a9dc6db3d7b53e1acebd9275677f4b0a04f1a5",
        ...
}
```
If you have not your Bittrex API key yet, 
[see our tutorial](https://github.com/freqtrade/freqtrade/blob/develop/docs/pre-requisite.md).


## Next step
Now you have configured your config.json, the next step is to 
[start your bot](https://github.com/freqtrade/freqtrade/blob/develop/docs/bot-usage.md).
