Any software developer, when looking at the level of
precision they need in their programme, first must
look at the data that the application will be handling.
If the data is accurate to, say, two decimal places, then
it is useless functionality to be able to deal with that data
to six places. The data that Tradestation deals with is
often not even accurate to two places.
It is also wrong from a system building perspective, as it
suggests an entirely incorrect level of detail is attainable.
So the demand that Tradestation should be accurate to
more decimal places is not only stupid, in that it focusses
attention on an 'improvement' that has no bearing on the
job the software is designed to do, but is also a symptom
of a state of mind that entirely fails to understand the real
level of accuracy that is attainable. These traders will fail.
Incidentally, to use Excel functions as demonstration is
laughable. Every statistician knows that Excel's functions
are basic in the extreme, and perform very badly on test
sets of sample data. The arithmetic may be correct but
the functionality is useless.
