Stock Splits

When a stock splits, you can fix your data in Aspen Graphics.  A split causes a sudden drop in the price and volume level of a stock.  The effect of a split is an inconsistent ratio between prices and volumes in your historical data and the prices and volumes of your current data. The split fix feature lets you adjust your historical data to the current price and volume ratio.

Fixing splits on a workstation affects data on a server, data that may be used by others, so great care must be taken to ensure correct results. You can only fix splits if your login has Data Editing permission (granted in Admin).

To fix a split, follow these steps:

1. Display a chart containing a stock that has split.
    

2. Enter the .FIXSPLIT command.
   
   
   In Personal Edition software, choose Fix Split from the Tools menu.
   
   The Fix Split menu is displayed.
   
   
    

3. Enter the stock symbol in the Symbol field.
    

4. Enter the date the stock split in the Split Date field.
    

5. Enter the numerator of the split ratio in the Split Ratio field.
    

6. Enter the denominator of the split ratio in the for field.
    

7. Select Fix Split. Aspen Graphics fixes the stock split.

When you select Fix Split, the Fix Split selection changes to Undo Fix.  If the ratio you used to fix the split was wrong, double-click on Undo Fix.  This restores the split so you can adjust the split ratio.

You must be careful to identify the correct split ratio when you are fixing a split.  Displaying a chart containing the split is helpful because it lets you see the results of your split ratio.
