Just curiosity, I am not planning to move to mathematica, but how much more
than Tradestation do these expensively written applications cost?
Bug seems to be a word that means more in english than some of us non
english speakers understand. I thought for example that if DMI is
implemented in the code by Omega, if the specification says it should add to
the sum only during certain circumstances, and it adds to the sum at some
other circumstances and not all of the circumstances in the specification,
that would be called a bug?
I knew IBM used to call things like that for "undocumented restrictions" but
I always viewed it as some kind of yoke.
So if a company (Omega) writes a package, advertises that it includes the
DMI indicator, and it does compute other results than those defined in the
DMI definition, due to their implementation of both math and the indicator
itself, is that to be called a limitation? What is then the definition of a
bug? If the DMI calculation halts? Nope, we have the missing divide by zero
check, it halts, so that must also be a limitation. What is a bug? When
Omega annonces "we had a bug and it is corrected"? Can bugs appear before
they are corrected or acknowledged by the vendor? I would have though a bug
was when the specification of what should happen is not followed?
