Hi Folks I am trying to plot displaced (2 stdev) simple moving averages (14 day) over a given lookback period (eg 60 days) from a given date enterd as an input, so that the bands catch 95% of the price action over the lookback period. The credit for the idea goes to Jose Siva - while playing around with his Linear Regression Trendline & Bands codes but trying to unravel his very clever code has got me beat. The issue for me is trying to nail the beginning and end of the plot. Below is the template for what I am tryig to do - have removed all my unsuccessful code clutter to make it easier to follow (I hope). If anyone has any suggestions I would very much appreciate it. The attached picture may or may not help to clarify the objective. (BTW I have overlayed Jose's plot Linear Regression Trendline & Bands as an indicator of the target area if that helps) Thanks in anticipation to anyone who can nudge me in the right direction. {User Inputs} pds:=14; LookBk:= 60; Day1 := Input("Day",1,31,5); Month1 := Input("Month",1,12,2); Year1 := Input("Year",1900,2400,2002); FstDate:=DayOfMonth() = Day1 AND Month() = Month1 AND Year() = Year1; BkDays:= Ref(FstDate, LookBk); MA:= Mov(C,Pds,S); { End date point - Credit to Jose Silva} end:=Year()>Year1 OR (Year()=Year1 AND (Month()>Month1 OR Month()=Month1 AND DayOfMonth()>=Day1)); end:=end AND Alert(end=0,2); end:=If(LastValue(Cum(Ref(end,pds)))=0, LastValue(Cum(1))=Cum(1),end); { Moving Average end-point } lastValMA:=LastValue(Highest( If(end, Mov(C,Pds,S),0))); { MA Segment } MaSeg:=Ref(Ref(MA,-LookBk),LookBk); {main} { Envelope bands } offset:= 2 * Stdev(H - MA, LookBk); HiBand:= MA+offset; LoBand:= MA-offset; {Plot} MA ; HiBand; LoBand;

Hi Asish Far be it for me to criticize Jose - the comment was for my benefit - not intended in any way to be derogitory. I have had number of attempts to solve this with varying code, and what I do to perhaps aid my request is to strip out my unsuccessful attempts at coding, in this case I overlooked some of the offending code. I do this as I am time poor and sometimes comments to myself help recall what has or has not been achieved, when I come back to the issue after some weeks between attemps. I have edited the above and removed the uneccessary code, as per your request. Ed

Maybe this post can be of help. jose '-

Sorry Ed - I've got no idea as to what you are trying to do. jose '-)

Ed, I'd like to help you, but unfortunately I can't find the extra time required to deal with the difficult intricacies of posting code, images and links in this new forum. Check out the "Indicator plot restriction" code available from MetaStockTools.com. jose '-)
