Ok, so you tell me that it should never plot a zero. Interesting. This based
on simple mathematics. Even more interesting.
Now, except for telling me that Tradestation works perfectly, which we all
know you will always tell us, please tell me what is wrong with expecting it
to plot zero. Feel free to express it mathematically if you like, I have no
problems with math, or explain the fault in the mathematical logic in any
other simple way you can.
Below is a simplified version of the code as i got it from Gary. The
original code was just a copy and paste from Omegas own dmi code. You can
use any version you like when explaining why the mathematical laws state
that this version of zero zero never plots as zero in Tradestation.
I asked for help, and you claim that you understand why it should not be
zero, and that it has nothing to do with Tradestation (and thus precision),
that it is correct maths to come to the conclusion of 0.107. Please explain
why. I am really eager to here you mathematical explanation. Please avoid
fuzzy logic.
******************************************
{Test Indicator, must plot Zero line}
Value1 = 10.387 - 10.280;
Value2 = 10.280 - 10.173;
If Value1 = Value2 Then Value1 = 0;
plot1 (Value1);
