WL For Supertrend in TOS

Mr. Hahn, I have the indicator code for Supertrend. Can this be made for a watchlist? Here is the code. Many thanks!

input AtrMult = 1.0;
input nATR = 4;
input AvgType = AverageType.HULL;
input PaintBars = yes;
def ATR = MovingAverage(AvgType, TrueRange(high, close, low), nATR);
def UP = HL2 + (AtrMult * ATR);
def DN = HL2 + (-AtrMult * ATR);
def ST = if close < ST[1] then UP else DN;
plot SuperTrend = ST;
SuperTrend.AssignValueColor(if close < ST then Color.RED else Color.GREEN);
AssignPriceColor(if PaintBars and close < ST

then Color.RED

else if PaintBars and close > ST

then Color.GREEN

else Color.CURRENT);

AddChartBubble(close crosses below ST, low[1], low[1], color.Dark_Gray);
AddChartBubble(close crosses above ST, high[1], high[1], color.Dark_Gray, no);
# End Code SuperTrendplot Data = close;
