Hi,
Cross function IS different from simple >=.
Cross( array1, array2 ) function checks the following:
array1(today) > array2( today ) AND array1(yesterday) <= array2( yesterday)
Please note that first part of the statement is "greater than"
and not "greater or equal"
For the stops: please download the latest version 3.60a
(http://www.amibroker.com/bin/ab360abeta.zip)
stops (profit target and max loss) work more precisely with this version.
Best regards,
Tomasz Janeczko
