Jayson,
No, that is not correct....
example: load into AA , select current ticker ( QQQ ) , n last quotation and
n=1
click explore....
X=H-(H-L)*.25;
Y=25.21-(25.21-24.71)*.25;//I inserted the high and low of the QQQ'S for
2/24/03.
Filter=1;
AddColumn(X,"X");
AddColumn(H,"H");
AddColumn(L,"L");
AddColumn(Y,"y");

Parentheses can be used to control the operation precedence (the order in
which the operators are calculated). AmiBroker always does operations within
the innermost parentheses first. When parentheses are not used, the
precedence is as follows (higher precedence listed first):
NoSymbolMeaning
1^Exponentiation
2-Negation - Unary minus
3*Multiplication
4/Division
5+Addition
6-Subtraction
7<Less than
8>Greater than
9<= Less than or equal to
10>=Greater than or equal to
11==Equal to
12!=Not equal to
13&Bit-wise "And" (AFL 2.1+)
14|Bit-wise "Or" (AFL 2.1+)
15NOTLogical "Not"
16ANDLogical "And"
17ORLogical "Or"
18=Variable assignment operator

Jayson,
Following on your example...Please check your equation...I am missing
something.
Filter = O>H-(H-L)*.25AND C>H-(H-L)*.25 AND
Open - 24.70
high -25.34
low -24.68
Anthony,
I made my calculations late last night (and they were wrong) but I "think"
it would be calculated like this......
open=24.70
h-(h-l)= (25.34-(25.34-24.68)= 24.68
24.68*.25= 6.17
so... 24.70>6.17
wouldn't you need another set of parenthesis....... (h-(h-l)*.25) to get
your answer ??
jayson
( open ) 24.70 > (high ) 25.34-((high)25.34 - (Low) 24.68) * .25 =
24.70 > 25.34 - (.66 ) * ..25 =
24.70 > 25.34 - ( .66 * .25 ) =
24.70 > 25.34 - ( ..1650 ) =
24.70 > 25.34 - (.17 ) =
24.70 > 25.17

I think there are several problems. Your filter for example........
Filter = O>H-(H-L)*.25AND C>H-(H-L)*.25 AND
In English you have .......
Open is greater than high minus the sum of H-L times .25 AND bla, bla
lets use today's QQQ as an example.....
Open - 24.70
high -25.34
low -24.68
so your filter would return
27.70 {the open price} minus .68 {the sum of H_L} =27.02
27.02 Times .25= 6.755
or
24.70>6.755 In this case QQQ fails the filter before it even looks at the
2nd part after the AND statement.......
In English what are you trying to do??

I am using this formula with scan test for now,but question is why is
this formula only coming back with penny stocks.
Plot( Close, "Price", colorBlue, styleCandle );
Buy = Cross(Close,O>H-(H-L)*.25 AND C>H-(H-L)*.25 AND
L<Ref(LLV(L,10),-1));
BuyPrice = H +.125;
BuyStop = H+1.125;
Filter = O>H-(H-L)*.25AND C>H-(H-L)*.25 AND
L<Ref(LLV(L,10),-1);
