Hi System Mixers, I've been following this thread. I see people want to do different things when they say mix systems. If all you want to do is backtest on daily bars with multiple systems, yet be able to test each system by itself first, one simple way might be to obtain each system's equity curve (preferably walk-forward OOS curve), and then export that curve to a CSV file.
Once you have say, 2 or more systems that you want to time / combine, you can then create a new AB database with nothing in it, and then import the equity curves as pseudo/fake symbols using just Date and Close, where the Close is your equity value from that system. Then you could write one code to rank or time the equity curves. Sure, that's quite a bit different than controlling and combining all the individual orders of all the systems, but if you want to keep your system's separate and just time their individual equity curves, then this sort of approach might work. The down side is that you wouldn't be able to see how much risk you are taking on 1 stock. Like, if all systems pile into AAPL Long, that might be pretty bad. Another down side is I could see it being a pain to update going forward. -Paul --- In [email protected], "Gonzaga" <gonzag...@...> wrote: > > Hi. > I am lately trying to mix several systems in on meta-system, and I am > observing that is not difficult to obtain good CAR's with low Draw Downs. > For example, system 1 trade against 100 tickers of the NAsdaq-100 and system > 2, against the same 100 tickers.
