Dave, I'm guessing, but I think the answer is that, since the first
condition is 0 and the second and third conditions would be equal
mathematically, then the second and third conditions would be used in the
calculation (i.e., you compare NAV with ref(NAV,-1), where NAV = O=H=L=C. That
would be the TR, and the average TR would then be calculated over a date range
using Wilder's smoothing.

Stockcharts.com says ATR is:Wilder started with a
concept called True Range (TR) which is defined as thegreatest of the
following:- The current high less the current low. - The absolute
value of: current high less the previous close. - The absolute value of:
current low less the previous close.And I think ATR is just an MA of
that. I'm with Al, I don't see how thatapplies correctly to
MFs.Ken, do you have a ticker list of the no-ERF funds from Fidelity?
If you do,I'd love a copy, either here or to dmerrill at usa dot
net.Thanks,Dave> ARF ARF. Sorry,
couldn't resist. ART should be ATR and FidoMFs are my> list of
Mutual Funds available at Fidelity with no ERFs (gasp - Early>
Redemption Fees).> > AB happily calculates ATR(x) on mutual
funds, so no problem there. I> assume the routine uses the
O=H=L=C that is true for all MFs. BTW,> ranking by SD and ATR
does not produce the same order of funds. Similar> in places,
