User-Defined Indexes (“UDIs” for short) are daily datasets that are created and maintained by a StockCharts member instead of by the StockCharts data team. Members of our Extra and Pro service can store any kind of daily time-series data inside a UDI and then use our SharpCharts charting tool to create charts of that data.
Examples of data that you might want to store in a UDI include:
The possibilities are endless.
Extra members can create 1 User-Defined Index with the fixed ticker symbol ”@MYINDEX”. Pro members can create up to 30 different User-Defined Indexes and can give each index its own unique ticker symbol.
User-Defined indexes can only store daily, weekly, monthly, quarterly or yearly data. They cannot store intraday data.
The UDI Workbench is the place to create, edit, and delete your UDIs. It allows you to enter a long and short description of your index, and for Pro users, pick the ticker symbol. From the workbench, you can either enter or upload the daily data for your index. You also have the ability to erase one row or all of the data in your index.
To access the UDI Workbench, go to the Members Homepage and click on the link for “User-Defined Index Workbench” located in the “Control Center” area on the page.
On the UDI Workbench, Extra members will see that they already have their one UDI created, with the ticker symbol ”@MYINDEX”.
Pro users will need to add UDIs manually. To create a UDI, click the New Index button. Enter the ticker symbol and long and short descriptions of your new UDI. Click Create Index.
To work with a different one of your UDIs, click on the blue Select Your Index drop-down menu and choose a different index.
To edit the long or short descriptions for the currently-selected UDI, click on the Edit Info button. Make your changes and click the green Save Changes button.
In the event you no longer need one of your UDIs, you can click the Delete Index button to remove the currently-selected UDI.
After you've set up your UDI, you'll want to add data. You can either add the data one row at a time, or upload several rows using a specially-formatted spreadsheet.
To add an individual row, click anywhere in the row of the data table that says “New Row” and fill in the information for that data point:
Once the appropriate fields are filled in, click the Save button to add the new row.
If you have many rows of data to enter, you can save time by creating a spreadsheet on your computer and uploading all the data at once.
The spreadsheet must be formatted a certain way in order to be uploaded into your UDI:
Once your spreadsheet is ready, click the Upload Data button on the UDI Workbench. Click Choose File, and locate the CSV file on your computer. Then click Upload.
To edit an existing row, mouse over the row you want to change. Two small icons will appear to the right of the row. Clicking the pen and paper icon will allow you to edit the row. Click Save once you have made your changes.
To delete a single existing row, mouse over the row you want to change and click the trash can icon to the right of the row. To delete all the rows in your User-Defined Index, click the Clear All Data button above the table.
Once you have data in your User-Defined Index, you'll want to chart that data. You can click the View Chart button on the UDI Workbench to launch a SharpChart of your UDI ticker symbol.
You can also add your UDI to any chart using the ticker symbol ”@MYINDEX” (or for Pro users, whatever ticker symbol you specified for the UDI when you created it).
