For one of my cross- (sanity?) checks I've installed 1.96 fresh into another directory and added the latest History files. When I Test those same 1.96 Z Systems, the results are no longer what they were (they're now worse). Comparing the equity curves, the differences start at the beginning - 2014 is a drawdown year now.
The only difference I can think of is the History files, since it's the same Zorro install file. Hence the question: Have the History files changed (presumably for the better) since 1-1.5 years ago?
