JingLarry,
You ask,
1)"........how do you know your system works?
and then you say,
2)"...There would be no way to know those optimized setting before hand.
and then
3)"...I just don't understand what all the hype is all about.
So I will answer your questions backwards.
3) What hype? There has been no "hype" in the classical sense of that word in my opinion. There has been an enthusiastic response, probably due to the fact that most people who have looked into X_DEV in more than a superficial way seem to recognize it's value. I see no grand claims being bandied about that X_DEV is the Holy Grail or the answer to everyone's needs. I even suggested as much myself only yesterday. So that statement needs to be retracted.
2) Of course their would be no way to know what the optimized settings would be before hand. That's why I developed X_DEV in the first place and that's why it is one of the main functions of the X_DEV system. To find out where the bands would have been to produce the best results so one can find the best targets in the present.
1) You should define what you mean by "works". If what you mean is "why is the system helpful in producing better results than most traders can produce without a balanced systematic mechanical approach to trading", than you need to re-read this thread and the available X_DEV information again.
