Object reference not set to an instance of an object at WebLink.ChartsFramework.Data.GenericSecurity. BullAlert history file corrupt.


This is a generic message so it is not sufficient to recommend a suitable solution.

One possibility is it may be that the BullAlerts history file is corrupt.

A second indication of the problem is that all the lists in the Security Manager are missing.


  1. Navigate to the BullAlerts folder.  From Tools/Preferences and select the File tab, then scroll to Alerts.

2. Select View Location.

3. Delete the file called TriggeredHistory.his

4. Restart BullCharts.
