Could you please provide more details about the issue
1) Did you get a error message? If so, please provide the text of the message. Please also check whether there are errors in the Events log (you can open it by choosing Show Events in the Strategies menu).
2) Please check whether the signal is in the list of available signals. For that, open the Add Strategy dialog (Strategies menu -> Add Strategy). You will see the list of signals. Scroll the list down and check if your signal is in the list. If must be in the Other group. To start the signal, you should add it by clicking the Add button in the Add Strategy dialog. Note that the signal won't be shown on the chart. You can see it in the list of started strategies (Strategies -> Manage Strategies):
I hope this will help.
