DT- The code is definitely misapplied if it is to have a practical
application. The fact that it gives an angle of 4 degrees in the QQQ
and 72 degrees in the ^NDX *for the same 27 periods* should be a huge
red flag for anyone with an open mind. The angles are dimensionally
incoherant and therefore meaningless, not only within the same stock
as its price varies, but especially in an exploration (and the code
contains an exploration). This is not a slam on Anthony at all, I
have the highest respect for him and his work, but rather a statement
of fact. You can continue to argue otherwise but I'm not going to
participate because I have better things to do.
