I think we have all tried every variation. I think MetaStock needs to
include at least an If Then function and perhaps a null function as well.

Nope, I tried that an it doesn't work; it returns a 0 when you plot forward
by x days.

I don't know how the inner workings of the code is set up.  But apparently,
it
is set up to provide a continuous rather than a discontinuous fuction.  Put
another way, it is set up to always plot a value, even if that value is
zero.  It may be beyond the current design limits to return a null or "no
point plot" value.

I think the thing to ask for is a "null value" function return which does
not plot!
