## List pairs/list markets
The `list-pairs` and `list-markets` subcommands allow to see the pairs/markets available on exchange.
Pairs are markets with the '/' character between the base currency part and the quote currency part in the market symbol.
For example, in the 'ETH/BTC' pair 'ETH' is the base currency, while 'BTC' is the quote currency.
For pairs traded by Freqtrade the pair quote currency is defined by the value of the `stake_currency` configuration setting.
You can print info about any pair/market with these subcommands - and you can filter output by quote-currency using `--quote BTC`, or by base-currency using `--base ETH` options correspondingly.
These subcommands have same usage and same set of available options:
```
usage: freqtrade list-markets [-h] [--exchange EXCHANGE] [--print-list]
[--print-json] [-1] [--print-csv]
[--base BASE_CURRENCY [BASE_CURRENCY ...]]
[--quote QUOTE_CURRENCY [QUOTE_CURRENCY ...]]
[-a]
usage: freqtrade list-pairs [-h] [--exchange EXCHANGE] [--print-list]
[--print-json] [-1] [--print-csv]
[--base BASE_CURRENCY [BASE_CURRENCY ...]]
[--quote QUOTE_CURRENCY [QUOTE_CURRENCY ...]] [-a]
optional arguments:
-h, --help show this help message and exit
--exchange EXCHANGE Exchange name (default: `bittrex`). Only valid if no
config is provided.
--print-list Print list of pairs or market symbols. By default data
is printed in the tabular format.
--print-json Print list of pairs or market symbols in JSON format.
-1, --one-column Print output in one column.
--print-csv Print exchange pair or market data in the csv format.
--base BASE_CURRENCY [BASE_CURRENCY ...]
Specify base currency(-ies). Space-separated list.
--quote QUOTE_CURRENCY [QUOTE_CURRENCY ...]
Specify quote currency(-ies). Space-separated list.
-a, --all Print all pairs or market symbols. By default only
active ones are shown.
```
By default, only active pairs/markets are shown. Active pairs/markets are those that can currently be traded
on the exchange. The see the list of all pairs/markets (not only the active ones), use the `-a`/`-all` option.
Pairs/markets are sorted by its symbol string in the printed output.
### Examples
* Print the list of active pairs with quote currency USD on exchange, specified in the default
configuration file (i.e. pairs on the "Bittrex" exchange) in JSON format:
```
$ freqtrade list-pairs --quote USD --print-json
```
* Print the list of all pairs on the exchange, specified in the `config_binance.json` configuration file
(i.e. on the "Binance" exchange) with base currencies BTC or ETH and quote currencies USDT or USD, as the
human-readable list with summary:
```
$ freqtrade -c config_binance.json list-pairs --all --base BTC ETH --quote USDT USD --print-list
```
* Print all markets on exchange "Kraken", in the tabular format:
```
$ freqtrade list-markets --exchange kraken --all
```
