Hi Russ,
I took a quick look at the alanhull
website and at first glance did not see anything about your indicator. I
guess I need to register… Anyways the indicator looked interesting
to me and I thought having the indicator above the prices would also be
beneficial, so I created a channel. For lack of a better name, I call it
a Hull channel.
What’s interesting about the Hull
channel is that it shows consolidation vs. trending pretty well. The
consolidation areas are bracketed by flat lines where the trending areas the
channel has a slope. The trending part of the channel is actually very similar
to a Keltner channel. Here’s the Hull channel code if anyone is interested:
//
// Hull
Channel
//
periods = Param("periods", 13,2,100,1);
ATRmult = Param("ATR mult", 2.5,1.0,6.0,.25);
LR = LinearReg(C,periods);
LR_ATRl = LR - (ATR(periods)*ATRmult);
LR_ATRu = LR + (ATR(periods)*ATRmult);
HClower = 0; // Hull Channel upper line
HCupper = 0; // Hull Channel lower line
for (i=periods; i<BarCount;
i++) {
if(LR[i] > HClower[i-1]) {
if(LR_ATRl[i] > HClower[i-1])
HClower[i]
= LR_ATRl[i];
else
HClower[i]
= HClower[i-1];
}
else
HClower[i]
= LR[i];
if(LR[i] < HCupper[i-1]) {
if(LR_ATRu[i] < HCupper[i-1])
HCupper[i]
= LR_ATRu[i];
else
HCupper[i]
= HCupper[i-1];
}
else
HCupper[i]
= LR[i];
}
Plot( HClower, "HC lower", ParamColor("HC color", colorWhite ), ParamStyle("HC
style") );
Plot( HCupper, "HC upper", ParamColor("HC color", colorWhite ), ParamStyle("HC
style") );
Regards,
David

Hi David
thanks for the code. Please check out www.alanhull.com.au. His online
tutorial is very interesting.
Kind regards
