Many thanks for your explanation , i get more understanding about cum().
Before receiving your code, i have been playing around with Highest(),
lowest(),hhv() and llv(). Since I'm tring to find the highest and lowest
value on a particular year. i have try :
If(year()=2004,highest(h),0) or if(year()=2004),lowest(l),0)
Althrough a value have plot in-between the year 2004 but the value (highest
or lowest ) is wrong, it does not plot the highest or lowest value between
year 2004. It plot the highest or lowest value since the first day loaded in
the chart.So I wonder is there any way to write code that can find the
highest or lowest value/prices in a given period (year).For example abc
share have highest at $ 3.00 and lowest at $ 0.90 in year 2004.
Thanks You !
mun wai.

init:=cum(1)=2;
This line of code finds the indicator's first valid signal (second
price bar), to be used later in the ValueWhen() function seeding.
Without this code "trick", the ValueWhen() will not plot anything (N/
A, null) for the chart's first year.
cum(1)=2 becomes necessary (and not cum(1)=1) because the use of the
Ref() function automatically makes the first plot unavailable (null)
thereafter.
Another choice would be:
init:=cum(IsDefined(nuYear))=1;
