| Hi, Can anyone write the code so the RSI fills in with a solid colour, in the overbought and oversold areas. I noticed a lot of USA chartists do this and it can make it easier to see as the charts flip through quickly. Perhaps this will be too hard. Not sure what happens when the o'bought area is half completed. It would have to have completed I suppose |

Yes that's not too hard. See if this is what you're after. MML is showing half completion. { Full RSI formula with areafill }n := input("Time period",14,1);nb:= n*2-1; {=wilder's smoothing }Su:= Ma(If(C-Ref(C,-1) > 0, C-Ref(C,-1), 0),nb,E);Sd:= Ma(If(C-Ref(C,-1) < 0, Ref(C,-1) - C, 0),nb,E);rs:=100-100/(1 + (Su/sd)); rs; rs1:= if(rs>=70,rs,70);rs2:=70;rs3:= if(rs<=30,rs,30);rs4:=30;[color =red; linestyle=dotted]70; [color =lime green]30; [name =RSI Top Fill; linestyle=fill; color=blue]rs1; rs2; [name =RSI Low Fill; linestyle=fill; color=blue]rs3; rs4; |
