Hello,
I instructed Marcin to find your original message and reply.
As for ApplyStop itself it has no known problems and
it is very nicely documented in the User's guide and
at http://www.amibroker.com/f?applystop
Your problems probably come from lack of coding experience
and as soon as we find your original enquiry we will reply via
support channel.
Best regards,
Tomasz Janeczko
