Standard deviation from linear regression curve?

[arod49]

Can someone make the linear regression curve indicator have standard deviation?

Here ya go. Not sure what you wanted it to look like so it just looks like the Bollingers

#LinearRegwithSTDevBands
#mods by WTF_Dude

input displace = 0;
input length = 9;
input price = close;

plot LinReg = Inertia(price[-displace], length);
LinReg.SetDefaultColor(GetColor(1));

input SD_length = 14;
input Num_Dev_Dn = -2.0;
input Num_Dev_up = 2.0;

def sDev = StDev(data = LinReg[-displace], length = SD_length);

plot LowerBand = LinReg + Num_Dev_Dn * sDev;
plot UpperBand = LinReg + Num_Dev_up * sDev;

LowerBand.SetDefaultColor(GetColor(0));
#LowerBand.setstyle(Curve.Long_DASH);
LinReg.SetDefaultColor(GetColor(1));
#LinReg.setstyle(Curve.MEDIUM_DASH);
UpperBand.SetDefaultColor(GetColor(5));
#UpperBand.setstyle(Curve.Long_DASH);

. I set standard deviation to the regular 14 length that the TD indicator uses by default.

thank you very much sir

no problem. let me know if you get any good results using it in a system
