I have long believed that a long strategy, and short strategy should have a very similar setup. Nearly a mirror image. I figured if I could find a setup that worked for both by just reversing the setup, that it would be more robust and exploit some underlining "rule" of the market. I have since come to believe this is a fallacy. Recently my results have shown that long and short setups need to behave very differently. For instance in a trend following strategy, the short side shouldn't look for as much of a pullback before entering.. whereas a long strategy should... Has anyone else come to this conclusion that the 2 should be vastly different setups?
