Spreads markets in general

I've been evaluating the platform and playing with backtester and noticing that most of the spreads have high win ratios for recent years ( > 2000) but going back further in time (< 2000) the losing years are more frequent even to the point of making a strategy non viable. So question is, why? Has something changed in markets generally? Is it a data issue? Is this a cause for alarm? Would like to get the groups thoughts on this. Thanks!

Hi, it can't be data issues, even the oldest data are verified and correct. Markets change over time, and what worked before, doesn't have to work now.
