Just corrected one careless error but it still does not work properly.
I forgot to wrap the Low in a selectedvalue function. With that corrected, the slope appears on the selected bar when I first apply the indicator. But as soon as I select another bar, a new value does not appear. And even if I go back to the original bar, no more values of slopes are visible on screen:
PlotText("Slope\ n" + NumToStr(SelectedVa lue(SlopeTest) ), SelectedValue( BarIndex( )), SelectedValue( L), colorBlack);
