You can configure your data-feed connections in Connections Tab of the main Overcharts window.
To configure a connection:
If your connection is NOT in the list or you want to add more than one connection of the same type:
Warning: Many connections require credentials (Username and Password) ISSUED BY DATA-FEED (NOT the ones you use to login to Overcharts!).
Once the configuration is complete, start connection by pressing the CONNECT button or by double-clicking on the connection. You are connected successfully if dots shown next to the connection are all green.
If there are red dots, hover over the “i” icon to view the error message.
