Importing Historical Data
TradingSolutions can import historical data from a wide variety of data sources and file formats. The term "historical data" refers to prices and other data that has occurred in the past. This is different from "streaming intraday data" which is imported into TradingSolutions while it is occurring.
TradingSolutions is normally used as follows:
1. Historical data is imported for one or more securities.
2. Models and entry/exit systems are developed based on this historical data.
3. Updated data is imported or streamed into TradingSolutions to generate current entry/exit signals based on these models and entry/exit systems.
Importing Historical Data
The initial importing of historical data is usually performed using the Import Data Wizard. This wizard walks you step-by-step through the following activities:
· Downloading new data from the Internet.
· Importing data from files on your computer
· Updating data you have imported previously.
This wizard can be accessed in several ways, including:
· Select Import Data… from the File menu.
· Select Import Data… from the context menu for a group in the Portfolio View.
· Select the Import Data button on the toolbar.
· Press the Import Data button on the Modify Group Dialog: Name page.

Historical data is also imported by the TradingSolutions Solution Service. The Solution Service automatically imports data, models, and commentary for several selected stocks.

Historical data is traditionally "split-adjusted". This means that the prices prior to stock splits have been adjusted so that the value of a single share remains consistent across the split.
