rocLen is 12. 
emaLen is 3. 
smaLen is 12. 
C is [close]. 
ROC is (C - valresult(C,rocLen)) / valresult(C,rocLen)*100. 
smaSqr is simpleavg(ROC*ROC,smaLen). 
ROCdev is sqrt(smaSqr). 
emaROC is expavg(ROC,emaLen). 
upROCB is ROCdev. 
dnROCB is  - ROCdev.

Code for the ROCB indicator is set up in the AIQ code file. Figure 10 shows the indicators on a chart of Apple Inc. (AAPL). The red line in the first panel is the upper ROC band and the green line is the smoothed ROC. In the lower panel, the red line is the lower ROC band and the green line is the smoothed ROC.
