# Exchanges

Before you start trading, you need to enter the exchange [API key](/wiki/about/supported-exchanges/creating-api-keys.md) and secret, as well as the trading fees level for each exchange.

To enter API keys, go to [**Profile** ](http://localhost:5000/profile)**> Exchanges**.

Select your [exchange](/wiki/about/supported-exchanges.md) and fill in all the fields for this exchange.

{% hint style="success" %}
The master key is just the API key you've registered for an exchange.

Using the same registered key for both the "master key" and "key" fields is OK.
{% endhint %}

## Market selection

If an exchange requires specifying a market type, you can only run pairs of that specific market type (futures, for example) in the same bot instance.

| Exchange         | Market options                                                                                                                                |
