I
stand corrected. Great example... It pays to read. My lack of understanding
explains why my code is generally wrapped in many layers of parentheses
:))

problem with formula/ or scan testJayson, No,
that is not correct.... example: load into AA , select current ticker (
QQQ ) , n last quotation andn=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
for2/24/03. Filter=1; AddColumn(X,"X"); AddColumn(H,"H");
AddColumn(L,"L"); AddColumn(Y,"y"); From the Users Guide.
Parentheses can be used to control the operation precedence (the order
inwhich the operators are calculated). AmiBroker always does operations
withinthe innermost parentheses first. When parentheses are not used,
theprecedence 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 Anthony -------Original

[amibroker] problem with formula/ or scan test 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 getyour
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 Anthony

Subject: RE: [amibroker] problem with formula/ or scan test 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?? Jayson Jayson
