Hi Keith and Roy,
If you add the close to your value '”bb”, you now get a always
positive value and you can use StDEV function after that.
And after the use of the StDEV, you substract the close...
a:=Mov(C,5,E);
b:=Mov(C,35,E);
bb:=a-b;
bb; { shown as histogram}
bb; { shown as a line }
bbc:=bb+c;
BBB:=BBandBot(bbc,20,S,2) - c;
BBT:=BBandTop(bbc,20,S,-2) -c;
BBB;
BBT;
I hope it can help you,
Pierre

Hi Keith
The problem with bb is that it swings through zero to negative.
Bollinger Bands are primarily for prices (I imagine) and so are
constructed to work only with positive data arrays. You need to
rethink how to approach your problem.
For what it's worth MetaStock has already told you what parameter is
causing the problem - bb is "value out of valid range", meaning that
it's not a positive value. It would appear that zero is also an
invalid value for bb.
Regards
Roy

I want to make a 5-35 osc with bands same as Advanced get
the 5-35 is no problem , histogram & line
I tried Std Error bands -- couldn't get them to plot properly
moved to StDev ( Bollinger Bands ) also won't plot
message is basically it's plotting out of range
can't figure that out as i'm trying only 2stdev
here my code so far
a:=Mov(C,5,E);
b:=Mov(C,35,E);
bb:=a-b;
bb; { shown as histogram}
bb; { shown as a line }
BBB:=BBandBot(bb,20,S,2);
BBT:=BBandTop(bb,20,S,-2);
BBB;
BBT;
can anyone see what my coding problem is please or offer any
suggestions--
thanks Keith
