Regrading the fix trade ratio, it is significantly easier to change the entry amount in your expert once it reaches $6000 instead of adding such option in FSB Pro.
Correlation coefficient sounds interesting, however it looks exactly as our "filter non-linear balance pattern" as Jetaro already answered.
You can open a separate topic for that and to explain the how it is calculated. If we find it the formula appropriate for FSB Pro we can implement it (I hope it will not take 3 seconds to be calculated ). You understand that every new feature makes the program slower and more resource demanding. Just compare FSB Pro to EA Studio and you will see. I'm totally convinced that the simpler systems work much better than the complex., however it took me 15 years of writing mathematical models and simulations to find it. But no, the users always want more complex.
My next program will be 14 gigabytes, will use 16 cores and will require 64 GB of RAM I'll make it 10 times more expansive and will call it FSB Enterprise. It will have menus with all the known terms in the industry. And guess, it will calculate a strategy for one hour. Even I can add a text box, where the users will be able to add their own terms and phrases for the menus.
Prepurchase open: now FSB Enterprise is 80% off - $7000.
