Thomas,
Please understand I don't debug / fix user's code because
it is exteremely time consuming and if I did I would not have time
to do anything more.
See http://www.amibroker.com/freesupport.html
I only can fix errors in AmiBroker itself if you provide me
with bug report showing incorrect calculations.
I looked at your code and you have lots of coding errors in it.
For example you write:
ExRemSpan(Buy, wait); // I thought I don't need
this unfortunatelly has no effect. ExRemSpan is a FUNCTION
and it's result value HAVE TO BE ASSIGNED to the variable.
Correct usage is:
Buy = ExRemSpan(Buy, wait); // ASSIGNMENT !!!!!!!!!!!!
Also ExRemSpans are placed incorrectly (they should be placed
before Cover = Ref(Short, -wait);, not after
etc, etc....
Best regards,
Tomasz Janeczko
