Signal Moving Average by LuxAlgo

[ApoZee]

I am trying to complete the code from tv to thinkscript but I cannot pass the error (invalid statement) in the green line. Help will be appreciated. This is the code from tv https://www.tradingview.com/script/L1NqQsyw-Signal-Moving-Average-LUX/



# Signal Moving Average by LuxAlgo

#

input length = 50;
input src = close;

def ma = 0;
def os = 0;

def target = SimpleMovingAvg(src, length);
def abs_diff = AbsValue(target - target[1]);
def bar = BarNumber();

def r2 = Power(Correlation(src, bar, length), 2);

def osCond = if r2 > 0.5 then Sign(src[1] - target[1]) else os;


def oc = osCond;
oc.AssignValueColor(if osCond == 1 the osCond else Double.NaN, Color.GREEN, Color.RED);

def nz = if IsNaN(ma[1]) then target else ma[1];

def maCond = if r2 > 0.5 then r2 * target + (1 - r2) * nz else ma[1] - abs_diff * os;


plot srcPlot = src;
plot signalMA = maCond;
AddCloud(if src > ma then src else Double.NaN, Color.LIGHT_GREEN, Color.LIGHT_RED);

Thank you for the help.

Used the previous template here and added just two extra inputs for customization of power and averagetype -- it does seem that having more sensitive average types can be better for capturing trend changes on higher time frames. As for the power, I'd suggest either 1 or 2 regardless.

input Length = 50;
input Src = Close;
input averagetype = AverageType.EXPONENTIAL;
def target = MovingAverage(averagetype, src, length);
def abs_diff = absvalue(target - target[1]);

input power = 2;
def r2 = power(correlation(close, BarNumber(), length), power);
def os = if r2 > 0.5 then sign(src[1] - target[1]) else os[1];
def ma = if r2 > 0.5 then r2 * target + (1 - r2) * (if isNaN(ma[1]) then Target else Ma[1]) else ma[1] - abs_diff * os;
plot plot0 = src;
plot plot1 = ma;
plot1.assignValueColor(if os == 1 then color.green else color.red);
def DeRec = Ma + 0; #
AddCloud(src, derec, Color.LIGHT_GREEN, Color.LIGHT_RED);
