RE: If Then function

Yes

The data array would be undefined if the statement were not true and nothing
would be plotted. The advantage to this is that we can break an indicator
into 2 or more parts to add color to the indicator.

neo,

If A > B then
    C = 10
Endif

is logically equivalent to :

If A > B then
    C = 10
( Implied Else )
    ( C is not modified )
Endif

It doesn't tell you anything about was C is supposed to be when A <= B

If you are expecting Metastock to not plot anything when A<=B, then you are
expecting C should undefined when the "IF" statement is FALSE, which is not
the same as "C is not modified"... Your implied logic is therefore :

C = Undefined
If A > B then
    C = 10
Endif

or

If A > B then
    C = 10
Else
    C = Undefined
Endif
