RE: Need Help on If Function....

["neo" <neo1@xxxxxxxxx>]

Alain

I tried your null:=ValueWhen(1,c<0,1) idea and you are correct, nothing gets
plotted. The workaround I am using is just to make Else=0. I then have a
null function which is just 0. I then use one If T E to plot above 0, a
second If T E to plot below 0, and the null to plot a thick gray line at 0.
As long as this is the last function plotted, it covers the wrong color of
the If T E statement. The moral of the story is that you can make an If Then
Else from 2 If Then functions but you cannot make 1 If Then from an If Then
Else statement.

Thanks, neo

We don't need a DLL to create a "NULL" function. Just write a simple
function that never produces a plot.

null:=ValueWhen(1,c<0,1);

Next, try to use it the following way in another custom indicator :

mva:=if(c>0,c,fml("NULL"));
mva;

What do you think will plotted ?
Answer : NULL ! [null literally absorbs the whole "if" function]

Conclusion : the Metastock "if/then/else" is flawed.

Make it work and no need at all for "if/then" stuff, really... Neither will
provide the elegant solution to your colour problem anyway.

Alain.
