HMA Arrow On Price

[draw9300]

Trying to get a crossover dot/arrow to show on the candles versus on the HMA line. This code doesn't work because the arrow signals are based on crossovers and not a single line

input price = close;
input length = 20;
input displace = 0;

plot HMA = MovingAverage(AverageType.HULL, price, length)[-displace];

HMA.DefineColor("Up", GetColor(1));
HMA.DefineColor("Down", GetColor(0));
HMA.AssignValueColor(if HMA > HMA[1] then HMA.color("Up") else HMA.color("Down"));


plot ArrowUp = if HMA crosses above HMA
               then low
               else double.nan;
     ArrowUP.SetPaintingStrategy(PaintingStrategy.Arrow_UP);
     ArrowUP.SetLineWeight(3);
     ArrowUP.SetDefaultColor(Color.Green);
plot ArrowDN = if HMA crosses below HMA
               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);
