That's strange. Here's the complete code from my version and it works fine for
every bar I click/select on:
SetBarsRequired(10000, 10000);
SlopeTest = LinRegSlope( C, 10);
PlotText( "Slope\n "+ NumToStr( SelectedValue( SlopeTest ) ), SelectedValue(
BarIndex() ), SelectedValue(L) , colorBlack);
_SECTION_BEGIN("Price");
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title= StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g,
Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1) ) ));
Plot( C, "Close", ParamColor("Color", colorBlack), styleNoTitle|
ParamStyle("Style") | GetPriceStyle() );
_SECTION_END();
Try copying/pasting this ......

Thanks but that does not make a difference as I already had that line
in my code.

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:
