need help removing extra arrows

[DAB721]

I am new to thinkscript I was wondering if someone could help
once one green arrow is printed how do I stop printing another green arrow until after a
red arrow is printed here is that part of the script if you need the rest let me know

input show_output_dot = yes;

def outup = (s1ok and s1up) + (s2ok and s2up) + (s3ok and s3up) + (s4ok and s4up) + (s5ok and s5up);
def outdwn = (s1ok and s1dwn) + (s2ok and s2dwn) + (s3ok and s3dwn) + (s4ok and s4dwn) + (s5ok and s5dwn);

plot zz1 = if show_output_dot and ((outup == cntok) or (outdwn == cntok)) then high * (1 + (1 * vert)) else na;
zz1.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
zz1.SetLineWeight(3);
zz1.AssignValueColor(if (outup == cntok) then Color.GREEN else if (outdwn == cntok) then Color.RED else Color.GRAY);
zz1.HideBubble();

This example might help. It is one way to limit the arrows as you want.

The image shows multiple arrows for plots up/dn in the same direction.
The plots arrowup/arrowdn limits the arrow plots when there is a change in direction/

#need help removing extra arrows

def ema8  = ExpAverage(close, 8);
def ema21 = ExpAverage(close, 21);

#Multiple arrows in one direction
plot up = if ema8 > ema21 then low else Double.NaN;
plot dn = if ema8 < ema21 then high else Double.NaN;
up.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
dn.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

#One arrow in each direction until a reversal arrow in the opposite direction
def cond = if ema8 crosses above ema21 then 1 else if ema8 crosses below ema21 then -1 else cond[1];
plot arrowup = cond[1] != 1 and cond == 1;
arrowup.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
arrowup.setlineweight(5);

plot arrowdn = cond[1] != -1 and cond == -1;
arrowdn.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_down);
arrowdn.setlineWeight(5);
