# Importing Tick Data

Historical tick data may be imported into MotiveWave™ by choosing ***Chart > Data > Import Tick 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.
* ASCII - Another popular and simple text-based file format.

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.
* **Replace Existing Data** – Replaces data that is already in the local historical database.
