This releates to 2000i - let's say you have a commodity whose price is 8
digits in length (e.g., Berskshire stock).......so if the close was
83674.56, Tradestation would round it in memmory to 83674.60.
Fortunately, when it plots the price data it uses the proper number and
if you do certain operations (e.g., close - close[1]) because the
resulting number will be relatively small it will be correct. However,
if I want to work with something like a moving average, you can't
(atleast with 100% accuracy).
I'm well aware of the issues with single precision in terms of large
calculations, but, up until now, I've never run into it being a problem
with prices. Any thoughts on how to handle it? THe only way I can think
of is by subtracting a large constant to scale number down to be able to
work with it.
