Hi NW Trader,
what I want is
1. LC = LLV(C,10);
2. C1 = Ref(C,-1);
3. Cond1 = IIf (LC==C1, True, False);
4. Cond2 = LC==C1;
Here ideally Cond1 and Cond2 should give same result but Cond2 sometimes giving result as TRUE even if LC and C1 is not same while
Cond1 is giving correct result, now my quest is why Cond2 s giving wrong results sometimes, thats it.
Regards
Abbas

Re: [amibroker] AFL Probs |
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 .

Re: [amibroker] AFL Probs |
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.

so i make an AFL like that
**********************************
LL = LLV( L , 10);
Prev_L = Ref(L , -1):
Cond1 = Prev_L == LL ;
*************************************
Now here Cond1 would be true only if Prev day's low is equal to lowest low of last 10 days,
but when i explore it given me signal wrong singal even i have chked it usign
I dont knwo it is happening , if some one can guide me where i wrong.
