Watchlist background color not matching chart

hi pete.

i have this indicator i am trying to adjust for my watchlist.

this is the code for the indicator:

input price = close;
input length = -10;
def displacement = (length / 2) + 1;
def dPrice = price[displacement];
def tmp = if !IsNaN(dPrice) then Average(dPrice, AbsValue(length)) else tmp[1] + (tmp[1] – tmp
[2]);
def tmp1 = if !IsNaN(price) then tmp else Double.NaN;
plot Data = tmp1;
Data.SetDefaultColor(color.CYAN );
Data.SetStyle(Curve.SHORT_DASH);
def pct=100;
input width=65;
def d=width/pct;
def d1=0.8*d;
def d2=1.05*d;
def d3=1.15*d;
def stdDeviation = Highestall(“data” = AbsValue(tmp1 – price));
plot UpperLine = tmp1 + stdDeviation*d1;
plot LowerLine = tmp1 – stdDeviation*d1;
plot UpperLine1 = tmp1 + stdDeviation*d2;
plot LowerLine1 = tmp1 – stdDeviation*d2;
plot UpperLine2 = tmp1 + stdDeviation*d3;
plot LowerLine2 = tmp1 – stdDeviation*d3;
UpperLine.SetDefaultColor(color.red);
UpperLine1.SetDefaultColor(color.red );
UpperLine2.SetDefaultColor(color.red );
LowerLine.SetDefaultColor(color.cyan );
LowerLine1.SetDefaultColor(color.cyan );
LowerLine2.SetDefaultColor(color.cyan );
AddCloud(UpperLine,UpperLine1,color.plum,color.plum);
AddCloud(LowerLine,LowerLine1,color.green,color.dark_green);

and this is me trying to get the watchlist to turn green when price is below LowerLine

and red when price is above UpperLine. but it does not work. i will add screenshots to help explain.

thank you for your time. -josh-

def tmp1 = if !IsNaN(price) then tmp else Double.NaN;
def Data = tmp1;
def pct=100;
input width=65;
def d=width/pct;
def d1=0.8*d;
def d2=1.05*d;
def d3=1.15*d;
def stdDeviation = Highestall(“data” = AbsValue(tmp1 – price));
plot UpperLine = tmp1 + stdDeviation*d1;
def LowerLine = tmp1 – stdDeviation*d1;

AssignBackgroundColor (if close > UpperLine then color.DARK_RED else if close < LowerLine then color.DARK_GREEN else color.CURRENT);
