Relative Strength MA and Stochastic Conditions

Hi Pete,

I had a previous question on the following Relative Strenght MA in this post https://www.hahn-tech.com/ans/relative-strength-ma-buysell-order/

Your help was appreciated!

I’m trying to use it as a condition in a watchlist with the stochastic .

Bullish Relative Strength MA and Stochastic would be in green, bearish in red and neutral is current.

But i get a few “Can not call setDefaultColor” , could you help ?

Also, when should plot statement be replaced with def and if yes why ?

#Stochastic
input fastLength = 12;
input slowLength = 26;
input MACDLength = 9;
input averageTypeMacd = AverageType.EXPONENTIAL;
input showBreakoutSignals = no;

def Diff = MACD(fastLength, slowLength, MACDLength, averageTypeMacd).Diff;

def slowMA = SimpleMovingAvg(“length” = 150).SMA[0];
def fastMA = SimpleMovingAvg(“length” = 10).SMA;

input over_bought = 80;
input over_sold = 20;
input KPeriod = 10;
input DPeriod = 10;
input priceH = high;
input priceL = low;
input priceC = close;
input averageTypeStoch = AverageType.SIMPLE;

def SlowK = reference
StochasticFull(over_bought, over_sold, KPeriod, DPeriod, priceH, priceL, priceC, 3, averageTypeStoch).FullK;
def SlowD = reference
StochasticFull(over_bought, over_sold, KPeriod, DPeriod, priceH, priceL, priceC, 3, averageTypeStoch).FullD;

#Relative Strength
input CorrelationWithSecurity = “SPX”;
input averageType = AverageType.EXPONENTIAL;
input length = 21;
def close2 = close(CorrelationWithSecurity);
plot RS = if close2 == 0 then 0 else close/close2;
RS.setDefaultColor(GetColor(6));
def sr = CompoundValue(“historical data” = RS, “visible data” = if isNaN(sr[1]) then RS else sr[1]);
plot SRatio = sr;
SRatio.setDefaultColor(GetColor(5));
plot ma = MovingAverage(averageType, RS, length);

plot value= if ma [0]> ma [1] and (SlowK > SlowD) then 1 else if ma [0] < ma [1] and (SlowK < SlowD) then -1 else 0 ;

AssignBackgroundColor (if 1 then Color.GREEN else if -1 then Color.RED else color.current);

Thank’s  !
