the ones like these below.. note - yours might have the word "Reversal .. with + price " i think . I removed that for only a "R:" on my bubble.
AddChartBubble((barnumber and U1), if isUp then low else high, if showarrows and signal > 0 and signal[1] <= 0 then "R:" else "" , if Colorbars == 3 then Color.PLUM else GlobalColor("MyBlue"), no); # Color.UPTICK, no);
AddChartBubble((barnumber and D1), if isUp then low else high, if showarrows and signal < 0 and signal[1] >= 0 then "R:" else "" , if Colorbars == 3 then Color.PLUM else GlobalColor("MyYellow") , yes);#Color.DOWNTICK, yes);
