# Connection to OANDA

{% hint style="warning" %}
OANDA doesn't provide tick data for Volume Analysis Data, that's why Volume Profiles or Footprint chart can not be used under this connection.
{% endhint %}

This guide helps you in a few simple steps to configure the connection to OANDA with the correct settings.

1. Open real or demo trading account with OANDA on their [**official website**](https://www.oanda.com/).

### Issues with connection

Sometimes OANDA cannot authorize users through API Key and you can see the message: *"**Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"***.&#x20;

To solve this issue, just click on the **Back** button and try to connect again. In most cases, the API key will be accepted and you will be successfully connected.
