Today there are many trading systems that offer various statistics on "how successful they are." The way to examine trading systems is not by looking at the winning trades but instead by looking at the losing trades. During a "bull run," anyone can create a system and it performs well. The person only has to be bullish over a long period. How will their system perform if the market all of a sudden reversed completely?
