'Variable can not deleted because it is in use' is wrong for this statement!
The variable in the Profit Target field has been replaced by another variable. Only after saving the EA is the variable that could not be deleted disappeared !? Here is a temporally corresponding error. Please eliminate. From my understanding, a change was not saved and the warning message appeared.
You can not see in the attachment that the variable is in use.
Var. 21 could not be deleted!
I bought the product SQX in April 2018. So far, I have not been able to produce a simple Expert Advisor that meets my quality standards and could be created with a working SQX-AlgoWizard software: The software is not working yet.
