 Ed,

May I ask as to why your scan is showing dates like 1 / 3 / 03...what are
your settings in AA for range....my settings are: n last quotations and n=1.

also, try this:

fourCrows_With_engul=Ref(C,-4) < Ref(O,-4) AND Ref(H,-4) < Ref(H,-
5) AND Ref(L,-4) < Ref(L,-5) AND Ref(C,-3) < Ref(O,-3) AND Ref(H,-3) < Ref(H
-4) AND Ref(L,-3) < Ref(L,-4) AND Ref(C,-2) < Ref(O,-2) AND Ref(H,-2) <
Ref(H,-3) AND Ref(L,-2) < Ref(L,-3) AND Ref(C,-1) < Ref(O,-1) AND Ref(H,-1)
< Ref(H,-2) AND Ref(L,-1) < Ref(L,-2) AND Outside()AND O < C;// AND H >
Ref(H,-1) AND L < Ref(L,-1);
Filter=fourCrows_With_engul > 0;
Buy=fourCrows_With_engul;
 Or try this:

fourCrows_With_engul=Ref(C,-4) < Ref(O,-4) AND Ref(H,-4) < Ref(H,-
5) AND Ref(L,-4) < Ref(L,-5) AND Ref(C,-3) < Ref(O,-3) AND Ref(H,-3) < Ref(H
-4) AND Ref(L,-3) < Ref(L,-4) AND Ref(C,-2) < Ref(O,-2) AND Ref(H,-2) <
Ref(H,-3) AND Ref(L,-2) < Ref(L,-3) AND Ref(C,-1) < Ref(O,-1) AND Ref(H,-1)
< Ref(H,-2) AND Ref(L,-1) < Ref(L,-2) AND CdBullishEngulfing()AND O < C;//
Outside()AND O < C;// AND H > Ref(H,-1) AND L < Ref(L,-1);
Filter=fourCrows_With_engul > 0;
Buy=fourCrows_With_engul;

Anthony,
 
Thank you for the very quick reply.  I copied your code into the 
Automatic Analyzer and and made one change. I did not state clearly 
in my description that I was looking for a close greater than the 
open on the most current day.  So I changed "O > C" to "C > O".  Then 
I ran a scan and partial results are listed below.  If you just look 
at any one ticker, say ACE. based on the code I would expect 4 red 
candlesticks and a green candlestick on 1/3/03 but that is not what I 
see on the chart.  Am I missing something?
 
Thanks,
 
Ed
