To see all alerts that have been triggered in the past 90 days, go to the Alerts History tab of the Alerts window. The alerts will automatically be listed sorted by date, with the most recent alerts at the top, but you can click any of the column headers to sort by that column. Mouseover a row to see a tooltip with more information about the alert.
If a single ticker alert was fired, the ‘Portfolio/Watchlist’ item for that ticker will be empty, but if the ticker triggered the alert for portfolio or watchlist, it will list which portfolio or watchlist. For example, in the screenshot below you can see that AAPL’s price increased 4% since the last close, which triggered the alert set for this scenario that was put in place for the entire David Einhorn portfolio. Just below that, there was a single ticker alert figured for when AAPL’s price fell below the specified amount. Because this second alert was just for AAPL itself, the Portfolio/Watchlist entry is empty.
You can delete an alert from your history by clicking the ‘x’ in the ‘Delete’ column.
To export the alert history to a .csv file click the ‘Export’ button in the top right hand corner highlighted in the screenshot below.
