Hi,

I need help in the CCI indicator. The thing is although there is already a CCI filter ready to be used, I do not want to use the ready made filter since I 'd like to experiment with changing variables within the CCI formula.

Can somebody please help me set up the program for doing the CCI filter from scratch? I'd like to change the constant as an experiment since I think I found a way to make it more accurate.

CCI = (Typical Price - 20-period SMA of TP) / (.015 x Mean Deviation)

Typical Price (TP) = (High + Low + Close)/3

Constant = .015

thanks in advance!

Here is a little diddy to get you started.

Fetcher[
set{hl, high + low}
set{hlc, hl + close}
set{tp, hlc / 3}
set{tpavg, cma(tp,20)}
set{tpx, tp - tpavg}
set{a, .015 x standard deviation(20)}

set{ccix, tpx / a}

draw ccix line at 0
draw cci(20) line at 0

symlist(spy)
]

I would think that the standard deviation would need to be on the typical price, not the close for this one. Something like this:

Fetcher[

set{hl, high + low}
set{hlc, hl + close}
set{tp, hlc / 3}
set{tpavg, cma(tp,20)}
set{tpx, tp - tpavg}
set{stdv, cstddev(tp,20)}
set{a, 0.15 * stdv}

set{ccix, tpx / a}

draw ccix line at 0
draw cci(20) line at 0

symlist(spy)

]



but to be honest, the curves are identical in action and crossovers. Not sure if this is any actual improvement over the standard indicator.
