In the figure shown below , I use ROC(C,1).
My need is the fact that I would like to explore stock in any watch list by what percent rate of change from start date to end date.
for example AAV
start date 1/8/18 price=4.62
to date 10/8/18 price=4.24
% rate of change =(4.24-4.62)/4.62 = -8.22%
I don't know how to implement in AFL or enable for using in window analysis.
I show this feature in Efinance (local app in my county );
Thank you in advance.
