Jose,
Are you still using these lines of code?

size=3>IIf(display=2,Plot(0,"",colorBlue,styleLine),Plot(Close,"",1,128));IIf(display=2,Plot(signals,"EMA
signals",colorRed,styleLine),Plot(EMA1,"EMA",colorRed,styleLine));----------
I believe, from the HELP files for the IIF()
function, you need to have IIF() return its value to some variable. The
following is from the HELP file for IIF:
"The following example shows one common error made with IIF function: IIF(
condition, result = 7, result = 9 ); // THIS IS WRONG
Correct usage is: result = IIF( condition, 7, 9 ); /* 7 or 9 is *returned*
and assigned to a variable depending on condition */ "

Subject: [amibroker] EMA/breakout signals
composite indicator
Please help this newie... :)I'm trying to get
the code below to display either the EMA with price, OR the crossover
signals, choice being through the Parameters (Ctrl-R) function. It
doesn't seem to work here, and it plots both instead.Any idea what I'm
doing wrong?jose
