Importing Data from eSignal

eSignal is an Internet-based service which provides market data to subscribers of their service.

TradingSolutions can download intraday, end-of-day, weekly, and monthly historical data over the Internet directly from eSignal. This allows you to keep all of the data in your portfolio up-to-date with the push of a few buttons.

TradingSolutions also supports importing real-time streaming intraday data over the Internet directly from eSignal. This allows you to get updated trading signals throughout the day while the market is open.

Configuring TradingSolutions to Use eSignal

eSignal is defined as a "data source" in TradingSolutions. eSignal requires you to sign up for an account in order to access data from its service. This account has a username and password associated with it, which TradingSolutions must be made aware of in order to access data through your account.

You can sign up for an eSignal account on the web. Special pricing may be available for TradingSolutions users. To see what deals are available and/or sign up, please visit the Data Sources section of the TradingSolutions website or jump straight there from the Configure Data Sources Dialog.

&  For help signing up for and configuring data sources, see Configuring Data Sources.

Ä    Note: eSignal software will need to be downloaded and installed on your computer in order to use eSignal for streaming data. This software is available from the eSignal website.

Importing Data from eSignal

New data series can be imported from eSignal using the Import Data Wizard and selecting Download new data from the Internet. This will display the Select Data to Download page, where you can select eSignal as the data source.

Ä    Note: These options will not be available if the eSignal data source has not yet been configured.

Existing data series can be updated from eSignal using the Import Data Wizard and selecting Update data in the target group. Individual data series are updated based on their currently selected data source. The data source for each data series can be viewed or modified from the Modify Data Series Dialog: Properties page. The data source for entire groups can be viewed or modified from the Modify Group Dialog: Properties page.

Streaming Intraday Data from eSignal

To stream intraday data from eSignal, it is recommended that you first download historical data for the symbol(s) you are interested in the periodicity or periodicities you would like to stream. This allows you to create any signals or other calculations before beginning streaming.

Once you have downloaded historical intraday data, turning on streaming will automatically update any intraday data which has not had the streaming option turned off.

&  For help with streaming updates, see Streaming Intraday Data.

Special Considerations with eSignal

TradingSolutions support with eSignal requires your computer clock to be synchronized with the eSignal server. By default, eSignal is configured to do this. This option in the eSignal settings should not be turned off.

Weekly and monthly data from eSignal is updated at the end of each day. On each day of the bar, the date and value of the current bar will be updated, resulting in new calculations based on these values. These calculated values should not be used until the bar is completed.
