the earlier discussion of using arrays as paremters to built-inindicators,
I need a version of the CCI that can take an array for
itsperiod.here's a description of how the 20-period CCI is
calculated, fromStockCharts.com: 1) Calculate today's Typical
Price (TP) = (H+L+C)/3 where H = high; L =low, and C = close. 2)
Calculate today's 20-day Simple Moving Average of the Typical
Price(SMATP). 3) Calculate today's Mean Deviation. First,
calculate the absolute valueof the difference between today's SMATP and
the typical price for each ofthe past 20 days. Add all of these absolute
values together and divide by 20to find the Mean Deviation. 4)
The final step is to apply the Typical Price (TP), the Simple
MovingAverage of the Typical Price (SMATP), the Mean Deviation and a
Constant(.015) to the following formula:
CCI = (Typical Price - SMATP) / (.015 x Mean Deviation)according to my
tests, this matches the built-in CCI exactly: MD =
0; // MD is Mean Deviation for(i = 0;
i < period; i++) { MD = MD + Abs(SMATP - Ref(avg,
-i)); } MD = MD / period;can anyone see how to do
the same thing with AFL array processing instead ofthe
loop?thanks,daveSend
