The negative is taken care of in the Bearish _expression_ – two negative
is a positive places it above the High.
Bull stop indicator is simply the following and ratchets up correctly:
InitStop:=Input("Initial
Stop",0,100000,0.50);
Index := 100-(100/(1+( PDI(21)/
MDI(21)+0.0001)));
OB:= Index-70;
Bullish:= CLOSE-(CLOSE*(OB/100));
Stop:= If(Bullish>=CLOSE,LOW
-(Bullish-CLOSE),LOW);
BullStop :=
If(Stop>PREV AND Stop>InitStop,Stop,
If(Stop>PREV
AND Stop<InitStop,InitStop,
If(Stop<=PREV,PREV,Stop*Holdingdays)));
BullStop;

Re: Short side Trailing Stop
Ed,
I actually like your thought process and would love to see the
bullish version. It might also help me to see the error.
About the OS. If you take a value of 30 and subtract the index from
it you will end up with a number that is less that zero most of the
time. This my be part of the problem.
We'll get it figured out.
