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.

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. Ara =============================================================== 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;
