Evo I have run a test myself and agree that the actual weekly and
timeframe inweekly are giving different results, not just more weeks
showing crossed but totally different values of the indicator for the
same period
I did a test and found that the value of Avg is not correct for your
use. replace it with calculated value and the dots line up, at least
as far as using expandlast allows
myavg = (H+L+C)/3;
Va2 = ((BBandTop(myAvg,20,2)-BBandBot(myAvg,20,2))/MA(myAvg,20))*100;
I suggest you advise AAB support of this discrepancy in calculation of Avg
