Help with script what am i doing wrong here?

the goal is to only get arrows when the 3ema crosses the 6ema above the 50ema

input price = close;
input fastLength = 10;
input slowLength = 20;
input averageType = AverageType.EXPONENTIAL;

plot FastMA = MovingAverage(averageType, price, fastLength);
plot SlowMA = MovingAverage(averageType, price, slowLength);
FastMA.AssignValueColor(if FastMA > SlowMA then else;
SlowMA.AssignValueColor(if FastMA > SlowMA then else;

plot ArrowDN = if FastMA crosses SlowMA < ema45
then high
else double.nan;

else double.nan;



Try This

input price = close;
input length1 = 3;
input length2 = 6;
input averageType1 = AverageType.EXPONENTIAL;
input averageType2 = AverageType.EXPONENTIAL;
input crossingType = {default above, below};

PLOT AVG1 = MovingAverage(averageType1, price, length1);
PLOT AVG2 = MovingAverage(averageType2, price, length2);
PLOT EMA50 = ExpAverage(price, 50);


signal.DefineColor("Above", GetColor(6));
signal.DefineColor("Below", GetColor(7));
signal.AssignValueColor(if crossingType == crossingType.above then signal.Color("Above") else signal.Color("Below"));

signal.SetPaintingStrategy(if crossingType == crossingType.above
    then PaintingStrategy.BOOLEAN_ARROW_UP
    else PaintingStrategy.BOOLEAN_ARROW_DOWN);

add this to the bottom if you want a paint bar.


AssignPriceColor(if signal == 1 && avg1> avg2 or avg1>avg2 && avg1 > EMA50 && avg2> EMA50  
then else if signal ==0 then Color.gray else Color.GRAY);
