Code question .

[T2020]

If this: [1]: displaces a Moving average one bar to the right .... Does this
[-1] displaced it one bar to the Left ? It verifies ,but nothing shows up on
a chart when I try to plot it ....

T2020,

[1] does not displace the indicator. All it does is access the value of the indicator on the previous bar. [-1] does not make sense as there is no bars at that index location.

OK , in the screen shot the Blue line represents :
fastEma.Set(SMA(Input, Fast)[0]);

And the Black line represents :
fastEma.Set(SMA(Input, Fast)[1]);

The black line appears to be offset one bar the right and there is a plot
on the current bar .
But I see what your saying ,you can't reference a bar that hasn't been
created yet . right ?

Correct. You cannot select a value to set your plot that does not exist yet.
