Hi Yves,
An addendum:
Iif you have looked up the construction of IIf statements, you will realize
that what I supplied was not correct. I do not know what you want to do if
result is not true, i.e., the false array you want to display. So what follows
is a completed IIf statement which simply makes the color change depending on
what you wanted for result. Of course I do not know how you define Result, so
until you define that, this will not work either (for my continued example, I
assume result is RSI(9) greater than 50).
Plot(RSI(9),"RSI", IIf(Result, colorRed,colorBlue), styleThick|styleDashed ) ;
A suggestion for construction: if you see what is needed in a plot statement
(e.g., color, make it a separate statement if you want the result to change
based on some condition and use that in your plot statement --
ColorRSI = IIf(RSI(9) >= 50, colorRed, colorBlue);
Plot(RSI(9),"RSI", ColorRSI , styleThick|styleDashed ) ;
Again, as has been suggested by myself and Mubashar Virk, read the manual.

Hi Yves,
If you insist on writing code, it is time for you to get out the manual and
learn the language (construction, reserved words, arguments and syntax) of AFL.
You ask questions which are at the heart of how to write even the simplest of
code. I solve this one for you:
Plot(RSI(9),"RSI", IIf(Result,colorRed,styleThick|styleDashed) ;
Note the different placement of the | symbol. Try looking up what "|" means
and it will make sense.
Here's a general hint: When you type a reserved word in the formula editor
(such as "IIf" ) and you then add the "(" , you will get the arguments which
you must supply and their order { i.e. type without the " ": "IIf(" and
IIf(Condition, TrueArray, FalseArray will display }. Try it with "Plot(" ,
"ParamColor"and "ParamStyle(".
Another hint - can't remember a reserved word? Start to type the first
letter, or several letters, and press <CTRL><Space> {press both the CTRL and
Space keys at the same time}. You will get a drop down menu of all the possible
ways to complete the word and you can select the one you wish. Of course there
is always "F1" available as well.
Take some time and read the manual and pay attention to the requirements of
AFL before calling something a problem. Lots of folks will help you with
coding, but few will be willing to teach you to read.

Subject: [amibroker] Problem with PLOT and IIF
I'm would have:
IIF(Result, Plot RSI in colorRed and styleThick, colorRed and styleDashed)
I'm try with that, but is NO GOOD:
Plot(RSI(9),"RSI", IIf(Result,colorRed,|styleThick,styleDashed) ;
Thank You
Merci
