Hello,
IIF is NOT a conditional statement. It is a FUNCTION that returns
values, therefore assignments inside argument part are wrong.
See it is listed in "Most common AFL mistakes" part of User's Guide
http://www.amibroker.com/guide/a_mistakes.html
Instead one should write:
rls = IIF( e < 10000, 100,
IIF( e < 100000, 500,
IIF( e < 1000000, 1000,
IIF( e < 10000000, 5000,
10000 /* otherwise */
) ) ) );
Best regards,
Tomasz Janeczko
