Shoot! It was late at night and English is my fourth language only.
The second line of my last reply does not read well. It should have been:
I understand what you mean by "how plain old FIR (finite impulse
response) can be proprietary", and I agree.

Hello,
I could "package" bread and butter, and sell it. But I can not claim
any intellectual rights to it. This is the point.
This indicator is not different that say MA(16). It is well-known
formula (yes simple moving average
is also FIR filter!) plus arbitrarily selected parameter (16).
Nothing more.
There are many freeware IIR and FIR "design" programs (even on line
like this:
http://www-users.cs.york.ac.uk/~fisher/mkfilter/
that allow you to enter cutoff frequency, passband ripple, etc
and so on and the result is just the set of coefficients, and even
C-source code ! so everybody can come up with zillions of
such "inventions" in a matter of 5 seconds.

Hi,
I did not say you added them. I just said you may/might remove them.

However, there are lots of guys out there busy packaging the open
stuff into "neural-networks" and other number generators, and selling
them as there own. Fin-Ware is one of the guys. They sell FATL,
SATL, etc. and the numbers/indicators generator software. Hence, the
assumption that they are (or may be) proprietary.

Hello,
The original poster (soni67c) added them.
With regards to 'proprietary' claim - could you explain?
I don't think that a plain old FIR (finite impulse response) can be
proprietary,
and the formula in question is nothing more than basic FIR filter.
http://en.wikipedia.org/wiki/Finite_impulse_response
Z-transform (which is core idea behind
digital filters like FIR) was introduced in 1952 (Ragazzini & Zadeh).
Applications to sampled data systems are known from 1955 (Lago, G.V)
1958 (Jury)

Fin-ware!
If not then TJ may have to take them out. These are proprietary
(and not for public disclosure), I think.

Thank you
