We both speak of facts, the same facts, but we stress different parts of
them since we have different starting points.
My starting point is that if we can keep a good clean agreement on what
should be improved in Tradestation, and make Omega and resellers understand
that there is a need a lot of people agree on, then we can do ourselves a
lot of good. At the same time, let us help less experienced users to
understand that these problems really affect them even in standard
indicators, by discussing them and how to avoid them (like Bob does, he
gives good advise). Your point is to me more of the theory lesson, it might
help some people to understand what they need to do to avoid problems but it
seems to me to have a lot of possibilities to instead make them think they
can be ignored, and a lot of possibilities to make Omega think they can
ignore them.
If I did not read your mail incorrectly, you did state that the speed
limitation is a good reason not to go to double precision, specially
considering that precision is enough anyhow. I do disagree on both of those
parts, both speed limitation being a good enough reason nowadays, and
neglecting the extra error introduced by staying at floating point
calculations.
However, what I want to speak most of is the same as before, if we keep
stressing we want Omega to do better with their handling of data results
caused by precision problems, we might get them to do that. If every time
somebody shows an example of precision problems not being dealt with by
Omega, we go into long discussions if this really has an outcome of trading
profits, we will cloud the message we otherwise would benefit to get
through.
I see Omegas neglect of handling precision problems in their code being the
same thing as neglecting to handle division by zero. They do not think it is
important, they do not get the impression the market considers it important,
and they will only do what they make profit from. If we keep saying to them
it is important, they may find a reason to rethink. If we instead say it is
good enough, they will not waste their money and efforts on handling it.
Then we will have to rewrite all the code ourselves to get it to do what it
should in the first place.
