You stated that you expect your system to show a 1000% profit in a years time, risking twice your initial capital. This sounds redicilious, but still, I am just curious, what is the basis of your analysis? A back test? Well, it suck's most of the time. A three day live demo test? Also does not count as a reasonable basis for anything. All of the 23 experts you included in your system can be trend oriented and show nice results on trends, but they can suck big time during sideways market, just as most indicators and experts do.
So unless you post the details to your system, the experts you use, the rules they follow, the money management strategy you plan to follow, the things you fix every day, and the basis to your systems profit ability analysis, there is no point in this discussion.
Or you want to discuss the advantages and disadvantages of expert advisor portfolio trading systems in general? Then clarify, what do you mean by that? Just a bunch of EA's combined in one system?
