One way to simulate a bear market is to create an "artificial price". 
For the S&P something like the following might work:

    Price = 2500 - Close;

As you can see, in a bull market, the artificial price heads down, 
simulating a bear market.

Of course, there is no assurance that the bar-to-bar patterns are 
representation of a bear market...

You can also check your system to see if it is symmetrical for up and 
down movements. Optimized systems usually are not and tend to favor 
an uptrend, since that is what we have been having.
