Hello,
Actually there are THREE solutions, two equivalent and third
one (Ara's) which just evaluates last bar instead of array.
SOLUTION 1: working on ARRAYS and using
IIFS:
range=<FONT
color=#000000>C/<FONT
color=#ff00ff>2; cond = (<FONT
color=#000000>H-<FONT
color=#000000>C < .1*range) Value1
= IIf( cond, <FONT
color=#000000>H, Value1 ); <FONT
color=#008000>// note that "else" condition assumes assigning the same value
-> no change, <FONT
color=#000000> <FONT
color=#008000>// but for that to work you would need to initialize value1...
earlier Value2 = <FONT
color=#0000ff>IIf( cond, <FONT
color=#000000>L, Value2 ); Value3 =
IIf( cond, <FONT
color=#ff00ff>2 * <FONT
color=#000000>C, Value3 ); Value4 =
IIf( cond, <FONT
color=#ff00ff>2 * <FONT
color=#000000>O, Value4 );
SOLUTION 2: Equivalent to above but
using looping. Please note that native AFL loops are FAST (20x faster than
JScript)
<FONT
color=#800000>for( i = <FONT
color=#ff00ff>0; i < <FONT
color=#000000>BarCount; i++ ) {
range=C[
i ]/2; <FONT
color=#800000> if( <FONT
color=#000000>H[ i ] - <FONT
color=#000000>C[ i ] < <FONT
color=#ff00ff>0.1*range ) {
Value1[ i ] = H<FONT
color=#000000>[ i ]; Value2[ i ] = <FONT
color=#000000>L[ i ]; Value3[
i ] = 2 * <FONT
color=#000000>C[ i ]; Value4[
i ] = 2 * <FONT
color=#000000>O[ i ]; } }
SOLUTION 3.
Suggested by Ara, but not equivalent to above solutions since conditional
expression evaluates ONLY one, the very last bar:
<FONT face=Arial
size=2> <FONT
face="Courier New">range=<FONT
color=#0000ff>LastValue(<FONT
color=#000000>C/<FONT
color=#ff00ff>2);
if
(LastValue(<FONT
color=#000000>H-<FONT
color=#000000>C<FONT
color=#000000>) < .1*range) { Value1 = <FONT
color=#000000>H<FONT
color=#000000>; Value2 = <FONT
color=#000000>L<FONT
color=#000000>; Value3 = 2<FONT
color=#000000> * C<FONT
face="Courier New">; Value4 = <FONT
color=#ff00ff>2 * <FONT
color=#000000>O<FONT
face="Courier New">; }
<FONT
color=#000000>
Of course LastValue can be replaced with SelectedValue
function if you prefer to calculate it depending
on selected value (marked vertical
bar) instead.<FONT

Re: [amibroker] If Then...
Hello,
This is because Close is an ARRAY in AFL (it is treated as
scalar in tradestation because tradestation runs your code MANY times (for
each bar),
instead of once like AMiBRoker).
I explained this in the past:
