Hi , I'm trying to fill Bollinger Bands with a pale solid colour but not had any success yet.
Checked out the code for MACD but it doesn't do anything for the BBands. Tried cutting out some of the code signal line etc but its obviously more complicated than that and how do you make FILL show in the BBands properties box
Any ideas

G'day Jalna

I had a look at the Hull Activest indicator which has a band fill. The last 2 lines here do the job. Giving the item a name allows access to it in properties.

n := input("Time periods",14,1);

sd := input("Standard Deviations",2,1);

[target=price]

[name=Top]

bt:=bbandtop(C,n,S,sd);

bt;

[name=Bottom]

bb:=bbandbot(C,n,S,sd);

bb;

[name=Average; linestyle=dash]

ma(C,n,S);

[name=Band Fill; linestyle=fill; color=blue]

bt; bb;
