The Don't Repeat Feature is useful when your Multi-Strategy Window displays many alerts for the same symbols in fast progression. This function helps to filter these repeated symbols. To access the Don't Repeat Feature, right-click into the Multi-Strategy Window, select Properties, and then Don't Repeat from the dropdown.
Now, you can select a time period, in which a symbol won't be repeated by any strategy within the Multi-Strategy Window, or choose not to repeat symbols at all. To define a Don't Repeat period for a selected strategy only, right-click into the Multi-Strategy Window, select Strategies, then choose a specific Strategy and select Don't Repeat from the dropdown.
