A next day Rydex 2x (or Profunds 2x) version would be a major improvement for a few reasons. First, there are many (including myself) who are stuck trading only these funds in account types where trading in stocks and options is not allowed. Second, accounts at Rydex or Profunds can switch among the Rydex or Profunds offerings without paying any commissions at all.
My experience with a number of Wealth Lab sripts is that the shorter the period, say 60 mins to 5 mins the higher the return. Some up in the 200% area with very short periods. Such a system may trade over 300+ round trips/year. I believe that is what has been experienced with the development of this system. I have used a WL short period system to trade OIH.
