Of course this involves working in the IT department of a brokerage house and light knowledge of SQL. Do a quick search for net losers in your system and find your persistent loser and do a little analysis on how often their stops are hit. You could also do winners and the stop hit frequency (possible title for that report field). Then you trade their stops. You could sell the information. Now, if you find someone whose stops are ALWAYS hit, make sure you keep them in the money with a home run every once in a while. You don't want that goldmine to run dry.
