I must admit I was quite surprised when I googled Boston Technologies that google prompted me with a frequently googled suggestion of "Boston Technologies Scam/Fraud"

couldn't help but try following those links...!
Also, re your quote: "each produces a few % a year to the total system results, giving a total above 30 % "
You obviously don't know "Maths" very well, for a total system to produce 30%, EVERY sub-system must make 30% as well!!
I'm afraid i'm starting to give up believing what you say, as you never seem to give any credible details, nor do you ever try to be "humble", it's always blasting away with the 1000pips/1000% stuff... Try it, you may find you get listened to more...
