The "issue" is I have many systems that are just slight variations of each other. Technically, I could reduce them down to one composite strategy but that would actually be more work as that would have to be done manually. For example, I just ran my research platform against ES using 30 minute and daily data. Out of 1,467,491 unique strategies tested, 249 strategies passed performance filters on all time slices of data. I will likely tighten up my performance filters because this is just one market regime for one target time frame (30 min) for ES. I could easily see myself having 1200 strategies like @MarkBrown.I cannot imagine having more than 20 systems running. I prefer a few very good ones instead of alot mediocre. It is already difficult to build 1 really performing system, so building a few hundred performing systems seems impossible to me.
