> Do we need to go out to the nth decimal place to decide what the price is?
Or is a good approximation (which is all that the price spotters can give us
anyway) good enough? I say that it makes no sense to run calculations out
to the nth decimal place when the input data is +/- 0.1 points.

Ha! It would not be the first time! Nor will it be the last!
It changes nothing... My point is the same, and I am correct.
It makes no sense to run calculations to the nth decimal place
when the input data is +/- 0.2 points. Anyone doing so is
fooling themselves.

trading is not more precision, but less. We need "fuzzy" approaches, not
precise ones. Carrying calculations out to the nth decimal place in a fuzzy
environment is ridiculous.

I do not know anything of this. But, again, it has no relevance to the
validity extra calculation precision. Such precision is wasted time and
wasted computing power.
