As you can see from my questions/answers, I'm always interested in finding new solutions. but quote me if I'm wrong: with your approach you are NOT using ONE equity pool.
Say you have 100k$, with your methodology you would do one of the following: Assign 50k$ or 50% to System1 Assign 50k$ or 50% to System2 ==> Backtest and combine equity curves as you said. Alternativley you might prop up "the result" in using 100k$ to backtest your 2 Systems. If you operate on a non-percent-risk model, it might work, but a non-percent-risk model ( e.g. fixed number of shares) is not really state-of-art. ...just thinking out loud... --- In amibroker@yahoogroups.com, "notanaiqgenius" <notanaiqgen...@...> wrote: > > Hi System Mixers, > > I've been following this thread.
