plot crossover arrows at HOD and LOD

[PAYtience]

Is there a way we can plot crossover arrows at HOD and LOD (or Way above or below the candle)?

def FastMA = average(close,50) ;
def SlowMA = average(close,200) ;
plot ArrowUp = if FastMA crosses above SlowMA
               then low
               else double.nan;
     ArrowUP.SetPaintingStrategy(PaintingStrategy.Arrow_UP);
     ArrowUP.SetLineWeight(3);
     ArrowUP.SetDefaultColor(Color.Green);
plot ArrowDN = if FastMA crosses below SlowMA
               then high
               else double.nan;
     ArrowDN.SetPaintingStrategy(PaintingStrategy.Arrow_DOWN);
     ArrowDN.SetLineWeight(3);
     ArrowDN.SetDefaultColor(Color.Red);
Alert(ArrowUp, " ", Alert.Bar, Sound.Chimes);
Alert(ArrowDN, " ", Alert.Bar, Sound.Bell);

input sPeriod = {default DAY};
def FastMA = Average(close, 50) ;
def SlowMA = Average(close, 200) ;
def varhigh = high(period = sPeriod);
def varlow = low(period = sPeriod);

plot ArrowUp = if FastMA crosses above SlowMA
               then varlow
               else Double.NaN;

ArrowUp.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
ArrowUp.SetLineWeight(3);
ArrowUp.SetDefaultColor(Color.GREEN);
plot ArrowDN = if FastMA crosses below SlowMA
               then varhigh
               else Double.NaN;

ArrowDN.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
ArrowDN.SetLineWeight(3);
ArrowDN.SetDefaultColor(Color.RED);
Alert(ArrowUp, " ", Alert.BAR, Sound.Chimes);
Alert(ArrowDN, " ", Alert.BAR, Sound.Bell);
