I know it must seem that way but that is not the case. People who
write complex TradeStation programs have to "work around" the limited
precision of TradeStation EVERY DAY.
But since the errors are not readily visible, most people never see
them and just wonder why they cannot develop a trading system that
works consistently...
The errors are not just "off by .0000000 to ..........umpteenth
power". In many calculation that subtract near-equal numbers, they
are off far enough to be easily visible on a plot. As an example the
attached plot shows a plot where the red lines are supposed to track
price. They are way off because of TradeStation precision errors.
In the next post (to avoid the size limit on posts) I will show a
picture of what it should look like after I "worked around" the
TradeStation errors.
