Tomasz,
I didn't speak for variable period but for variable item in the
function StrExtract( list, item ) .
In
y=StrExtract( "AAPL,INTC,MSFT", 2);
Title=y;
the title of the IB window is MSFT.
In
n=IIf(Cum(1)<200,1,2);
y=StrExtract( "AAPL,INTC,MSFT", n);
Title=y;
where n is variable, I was expecting a title INTC for the first 200
bars and MSFT for the rest.
In this sense StrExtract() does not accept variable n [although n is
an integer 0<=n<=2].
The problem appears when, at the end of the code, I know the function
of D, the ordinal # of a stock in a Group and I want to see the name
of the stock . In my Group254 I have 101 stocks and the respective
ordinal # 0 to 100.
I know, for example, that D=47 till 1/1/2001, D=56 till 1/1/2002 and
D=93 for the rest of the available data.
In other words D is an array with every D[i] in the 0,100 range.
At this point, I tried [unsucessfully] to use StrExtract( list, D) to
see the name of the stock written on the title of the pane.[A title
like "The Highest Equity stock from...to...was ORCL." What I can have
now is "The Highest Equity stock from...to...was # 47." ]
I hope it is more clear now...
[In AA there is a solution through
Status("STOCKNUM")==D
condition, since all stocks are selected. It can not be applied in
IB, because Status("STOCKNUM") is always 0, as it should be when we
select one, single, ticker from the symbol tree]
