You thought right--<SPAN
class=860232817-30042004>it is due to insufficient # of bars<SPAN
class=860232817-30042004>.
RankArray <SPAN
class=860232817-30042004>will work fine because AB throws out tickers
if the bar is
unavailable.RankNum fails because AB doesn't throws out tickers
if Price[BarCount-1-251]) is unavailable.SetBarsRequired( m,n )
only controls how many of the available bars get loaded<SPAN
class=860232817-30042004>: E.g., the help example:
setbarsrequired( 100000, 100000 ) // require all past and all future
bars
If you want RankNum, then you need to
correctly test that the ticker has enough
bars!-----Original Message-----From: mickeyamelinckx

a hand with solving this error I get with sometickers on the formula below
????This is the error I´m getting ! I thought this was due
to toolittle data, so I added SETBARSREQUIRED but this did not solve
thething, I guess because of the filter already included !I thank
you !!!!Line 14, Column 29:RankNum =
