# Importing

*Note: this documentation was written for running BlueBot via the command line. If you are using the UI you can simply use the importer under the "local data" tab.*

If you want to use BlueBot to [backtest against historical data](./backtesting.md), you most likely need some historical data to test against. BlueBot comes with the functionality to automatically import historical data from some exchanges. However, only a few exchanges support this. You can find out with which exchanges BlueBot is able to do this #### TO CHANGE #####[here](https://github.com/askmike/gekko#supported-exchanges).

## Setup

For importing you should [enable and configure](./plugins.md) the following plugin:

 - candleWriter (to store the imported data in a database)

Besides that, make sure to configure `config.watch` properly.

## Configure

In your config set the `importer.daterange` properties to the daterange you would like to import.

## Run

    node bluebot --import

The result will be something like this:

    2016-06-26 09:12:16 (INFO): I'm gonna make you rich, Sonic.
