Ken,
Yes, now it is much more clear.
You can simplify your code using for loop that
way:
<FONT
color=#000000>for<FONT
color=#000000>( i = 19; i
>= 0<FONT
color=#000000>; i-- ) { array = <FONT
color=#0000ff>Ref(
bTot, -i ); bkColor = IIf<FONT
color=#000000>( array <3<FONT
color=#000000>,colorRed<FONT
face="Courier New">,
<FONT
color=#0000ff>IIf(array ><FONT
color=#ff00ff>3 <FONT
color=#000000>AND array < <FONT
color=#ff00ff>5,
colorYellow<FONT
color=#000000>,colorGreen<FONT
face="Courier New">) ); <FONT
color=#0000ff> AddColumn( <FONT
color=#0000ff>Ref(BTot,-i),<FONT
color=#ff00ff>"-"+i,<FONT
color=#ff00ff>1.0,<FONT
color=#000000>colorBlack<FONT face="Courier New"
color=#000000>,bkColor); }
<FONT face="Courier New"
size=2>
This will give all
20 columns from -19 to 0.
<FONT face="Courier New"
size=2>
Hope this helps.
Best regards,Tomasz Janeczkoamibroker.com

Statements with FOR (?)
You guys are great,
and I apologize for not describing the high-<SPAN
lang=en-us><FONT face=Verdana
size=2>level<FONT
face=Verdana size=2>
goal.
There is an "animal"
in the FastTrack world called a "Cheese" chart, a glimpse of which is
attached. I also think that Bill Barack posted code for this in the
files area. In making a cust<SPAN
lang=en-us>om system<SPAN
lang=en-us> using
this<FONT face=Verdana
size=2> cheese chart<SPAN
lang=en-us> construction<SPAN
lang=en-us>,
I <FONT face=Verdana
size=2>needed to use much<SPAN
lang=en-us> more complex color
combinations<FONT
face=Verdana size=2>. P<SPAN
lang=en-us>lus<SPAN
lang=en-us> I
saw<FONT face=Verdana
size=2> the opportunity to practice something I do not use -- for
loops.
I could construct
(and have constructed the code that makes the attached) with a long series of
statements with Ref(XXX,-y) , 19 of them.<SPAN
lang=en-us> I copy one of
them, and then use Search/Replace to quickly alter each remaining
statement. <SPAN
lang=en-us> I thought I could make smaller
code<FONT face=Verdana
size=2> without copy/paste/edit.
In my example, I am
creating the color variable, A0, A1, A2, etc<SPAN
lang=en-us> (which is shown
as nc19, nc18<FONT
face=Verdana size=2>,<SPAN
lang=en-us> etc below)<SPAN
lang=en-us>
Then later, I use it
in an AddColumn Statement, like this
<FONT face="Courier New" color=#0000ff
size=2>AddColumn<SPAN
lang=en-us><FONT face="Courier New" color=#000000
size=2>(<SPAN

This is my actual
AddColumn code, but in my simplified example, I changed ncX to Ax, and BTot
was Tot (which of course is defined further up in the
logic).
<FONT face=Arial color=#000000

Does this make it
more clear?

Problem is that I
don't know what exactly Ken was after.
I provided some
explanation based on wild guesses.
Let us wait for Ken
to get back to us, describing the high-level goal
so we can help him
better.

The "A"s are arrays, so the A[i] seemed like the right way to go,
