Ed,
I'm seeing a problem with the following:
Bullish:= CLOSE-(CLOSE*(OB/100));
Stop:= If(Bullish>=CLOSE,LOW -(Bullish-CLOSE),LOW);
Bearish:= CLOSE-(CLOSE*(OS/100));
Stop:= If(Bearish>=CLOSE,HIGH +(Bearish-CLOSE),HIGH);
Notice that in both instances whether bullish or bearish we have the
close minus the close times the index percentage. Since we know that
Bullish is okay then Bearish should be
Bearish:= CLOSE + (CLOSE*(OS/100));
I am not at my home computer right now so I can't visualize this in
metastock but will as soon as I can.
The stop variable may also need to be changed as well. I just don't
know off the top of my head.
The index indicator is a different approach to the directional
index. Typically we normalize it like a stochastic. In your case it
is indexed like a RSI. I like the idea and certainly think its
useful. Its new and different.
I am sure we will get the problem resolved shortly.
