You have a plot to spare so I'd probably use an erase dot as plot3. Make
the Stoch plot4 so the black dot can't hide it.
vars:  Stoch(0), GreenDot(False), RedDot(False);
Stoch = SlowK(20);
GreenDot = Stoch > Stoch[1] and Stoch < 30;
RedDot   = Stoch < Stoch[1] and Stoch > 70;
if GreenDot then plot1(70, "Green")
  else plot3(70, "Black");
if RedDot   then plot2(30, "Red")
  else plot3(30, "Black");
plot4(Stoch, "Stoch");
