# Importing Data

Historical data may be imported into MotiveWave™ by choosing ***Chart > Data > Import Data*** from the top Console menu bar. Two types of data formats are supported:

* **CSV** – Comma Separated Values. This is a very common format for many historical data services. The format of the data file will be automatically detected when specifying files of this type.
* **MetaStock™ Database (Files or Directory)** – MetaStock™ Database files or directory containing 1 or more instruments may be imported into MotiveWave’s historical database.

This dialog has the following elements:

* **Data Files** – Specify one or more data files by clicking on the Add button to left of the Data Files list.
* **Time Zone** – Choose the time zone for the input file. This is important for resolving the data/time values for each historical price bar in the input file.
* **Exchange** – Optionally Choose the Exchange for the instrument(s) in the input file(s).
* **Trading Hours** – If a value is chosen for Trading Hours, it will be assigned to the instrument when it is created from this dialog.
* **Adjust for Stock Splits** – If the file does not contain split adjusted values, this will detect and adjust historical prices for splits.
* **Automatically Create Instrument (Do Not Prompt)** – If the instrument does not already exist in the local database, it will be automatically created if this is checked.
* **Replace Existing Data** – Replaces data that is already in the local historical database.
* **Monitor Input File For Changes** – If checked, MotiveWave™ will monitor the timestamp on the input file to see if it changes in the future. If it does change, the new data will be automatically loaded into MotiveWave™ when a chart is loaded.
