There is some merit to testing with hedging turned on though even if your broker does not allow it: Sometimes a lucky sequence can occur where some good trades luckily prevent some bad trades from happening just because the good trades were opened first, having an option to test with hedging turned on could help to spot these by allowing more trades in to the same sample. The stop and reverse solution can only apply to market strategies and isn't quite the same, plus it's no easy task turning stop and reverse on and off for hundreds of strategies.
EDIT:
Never mind! The answer is "Allow Duplicate Trades." ("Allow Hedging" might've been a better name...)
