I have used MetaStock for about 18 years and I can tell you that
their backtesting capabilities fall far short of those in Amibroker.
As Tomaz and the report he linked to on searchwarp both stated, all
MetaStock backtesting is limited to single-security testing. It has
no capability to do security selection nor can it properly handle
multiple positions in a portfolio.
