Chartsy|One is capable of downloading historical market data from various external data providers, including Yahoo Finance services (both EOD and intraday data is supported) and Tiingo services. The historical market data is always downloaded and stored in the Quote Databases, you have previously created and configured.
The supported historical data services are accessible from the Services tab. If the Services tab is not visible open it by using any of the following method:
- Select Window, Services from the program main menu.
- Click the Services button on the program main toolbar.
- Press the Ctrl+5 key combination.
Once the Services tab is opened, the list of available service connector groups is displayed. Expand the Historical Data group to show the list of all historical data connectors currently installed.
To configure the Historical Data service connector, right click on the specific node under the Historical Data group (e.g. Tiingo) and click on Properties in the context menu, as shown on the image above.
The Properties window will be opened in which you can specify any settings required by the specific connector. For example the Tiingo connector will require an "API Token" property to be set.
Hint: alternatively if you prefer the Properties view to be always opened, you can achieve this by selecting Window, then IDE Tools, then Properties.
To establish the connection with the external data provider:
- Right click on the specific service connector node, you want to use.
- Select Connect from the context menu.
If the connection was successful the icon of the connector will change color from black to green.
