Sat,
Seems simple enough, we should be able to simply display an indicator
sometime in the future. Problem is that using an if statement means
we would need something else in its place while we are waiting on the
date. The Gann Hi-Lo was an example of how this was done using one
display or another.
The restricted display indicators that I wrote displays after the
fact and only for a designated period of time. There are now three
versions of the indicator. One based on regular or standard date,
numerical date, and period of time. So what happens when there is no
display? You get a NA for a value, which means there was not enough
data to calculate.
Here is a date version:
{Restricted Display by Date v2.0}
{Written by Preston Umrysh}
{Displays an indicator within specified dates}
{Uses standard date inputs}
{Indicator} {Place your indicator/s here}
Ind:=MACD();
Ind2:=Mov(MACD(),9,E);
Sd:=Input("Start Day" ,1,31,1);
Sm:=Input("Start Month",1,12,1);
Sy:=Input("Start Year" ,1980,2015,2003);
Ed:=Input("End Day" ,1,31,31);
Em:=Input("End Month" ,1,12,12);
Ey:=Input("End Year" ,1980,2015,2004);
startdate:=Year()>SY OR
(Year()=SY AND Month()>SM OR
Month()=SM AND DayOfMonth()>=SD);
enddate:=Year()<EY OR
(Year()=EY AND Month()< EM OR
Month()=EM AND DayOfMonth()<=ED);
start:=startdate AND Alert(startdate=0,2);
end:=enddate=0 AND Alert(enddate=1,2);
{Restricted Display}
DisPds:=LastValue(Cum(1) - ValueWhen(1,Start,Cum(1)));
BackPds:=LastValue(Cum(1) - ValueWhen(1,End,Cum(1)));
Dispds:=Dispds-BackPds;
ResPds:= Alert(BarsSince(Cum(1)=LastValue(Cum(1)-
(DisPds+BackPds))=1),1);
Plot:=ValueWhen(1,ResPds,Ref(Ref(Ind,-BackPds),BackPds));
Plot2:=ValueWhen(1,ResPds,Ref(Ref(Ind2,-BackPds),BackPds));
Plot; Plot2;
{end}
Everything that you need to produce your indicator is there. I won't
restrict the display but will ask the indicator to display some time
in the future.
Let's try something like this:
{Indicator}
Ind:=MACD();{Place your indicator/s here}
Sd:=Input("Start Day" ,1,31,1);
Sm:=Input("Start Month",1,12,1);
Sy:=Input("Start Year" ,1980,2015,2009);
startdate:=Year()>SY OR
(Year()=SY AND Month()>SM OR
Month()=SM AND DayOfMonth()>=SD);
start:=startdate AND Alert(startdate=0,2);
DisPlay:= ValueWhen(1,Start,Ind);
Display;
{end}
If you compare the indicators you should be able to see the parts of
the original that I used. Let me know if this is what you had in mind.
