Very strange here: I just applied an indicator on an indicator, in this case Bollinger Band on RMI indicator. When, and only when, the B bands are squeezing, do I have this: the value of the BBand top and bottom totally change, FOR THE SAME BAR, when I scroll the chart a little bit to the left or to the right. No only does the value changes but I can see the change on the chart with the BBand having its shape modified.
Below is the formula, can someone explain this ???
Many thanks,
Carl

period = Param( "Period", 20, 1, 200, 1 );
momentum = Param( "Momentum", 5, 1, 200, 1 );
uplevel=Param("uplevel",66,50,100,1);
downlevel=Param("downlevel",34,0,50,1);
Plot( RMI(period, momentum), _DEFAULT_NAME(), ParamColor( "Color", colorBlack ), ParamStyle("Style"),0,-1 );
PlotOHLC( RMI(period, momentum),RMI(period, momentum),50,RMI(period, momentum), "", IIf( RMI(period, momentum) > 50, colorGreen, colorRed ), styleCloud | styleClipMinMax, downlevel, uplevel,0,-1 );
