Hello Ara,
i have checked your code and it works.
Maybe you have different parameter values in AA and Chart, because they are
not connected.
So If you change your NumDevs parameter in AA, it will not be changed on the
chart and if you change it
in the chart, it will not be changed in AA.

Subject: [amibroker] AFL - screen for outliers
I am trying to do a simple screen to find issues that are outside 3 standard
deviations of Bollinger band.
The code below seems to work .. of sorts, but when I plot the chart, the
results are not outside the bands.
Appreciate another pair of eyes looking at this.

===============================================================
NumDevs = Param("NumDevs",3,1,4,1);
Top = BBandTop(C,20,numdevs);
Bot = BBandBot(C,20,numdevs);
HiLo = IIf (Close > Top,1,IIf(Close < Bot,-1,0));
PlotOHLC(Open,High,Low,Close,"",colorBlack,styleCandle);
Plot(Top,"",colorRed,styleLine);
Plot(Bot,"",colorRed,styleLine);
//
//
Filter = HiLo ==1 OR HiLo ==-1;
AddColumn(Close,"Close");
AddColumn(HiLo,"HiLo");
"Close " + Close;
"Top " + Top;
"Bot " + Bot;
