Hi Abbas Ali,
I guess I don't know what you mean by "filter out". But here is
another stab at it. Do you mean identify when yesterday's close is equal to the
low of the 10 days prior to yesterday? While similar, this is a little
different from your original request which asked about Low values, not
close values.
If so, then the code I sent for LL2 could be modified to substitute C for
L. Thus:
Cond = Ref( LLV( L, 10), -2) == Ref(C , -1);
What you have posted says that Cond is true when yesterday's close is
identical to the lowest low value of the previous day's close over the past 10
days. Again an identity. Your mistake remains in the construct of
LLV. Read the AFL explanations for Ref and LLV.
Suggestion: Visualizing what you want by writing your condition as a
plot statement and/or as code to put a shape on a simple bar or candle
chart. Then if it doesn't look correct, tweak that code. In learning
AFL, it is often best to work with being able to show what you want on a chart
before proceeding to explorations, trading systems, etc. But then, I'm a
visual learner.

Dear NW Trader,
Thanks for ur reply.
But still my prob is not solved,
what i want is TO FILTER OUT DATA WHICH HAS ITS PREV CLOSE EUQAL TO LOWEST
CLOSE IN PAST 10 DAYS.
I know it is very simple like this.
Cond
= LLV(Ref(C,-1),10) == Ref(C, -1) ;
but it is giving me false data
where lowest close is 2,3,4,5,6,7, 8 or 9 bar ago !!!!!
I m confuded
.

I do not know if the following clues will help; I hope so. I can't be certain
what it is

Hi Abbas,
I do not know if the following clues
will help; I hope so. I can't be certain what it is that you are trying to do
as your explanation was truncated or incomplete.
LL = LLV(L,10); // This will return the lowest
low of the past 10 bars, including the most recent bar and yesterday's bar as
well.
LL2 = Ref( LLV( L, 10 ),
-2) ; This will return the lowest low of the 10 bars prior to 2 bars
ago.
Thus your code is checking
to see if yesterday's low is equal to itself (which it will always be). If you
want to see if yesterday's low is equal to the lowest low of the 10 bars
preceding it, use LL2 stated above.
As to your two prior questions that went unanswered, AFAIK, the title
statement can only handle text, not shapes. You can do different colors,
values and messages (such as a green "BUY", a yellow "Setup Condition Met",
etc.). As to the display in the ticker box, contact AB support as that is
beyond my usage and I do not do the Indian markets.
