Re: [amibroker] Using IIF statement

["Joe Landry" <jelandry@xxxxxxxxxxxxx>]

Hope you don't consider this out of line but  - and just a suggestion as you're starting out  - keep it simple, break the logic in easy pieces.   It makes it easier to read and to understand.

Periods = Param("Period",20,0,50,1);

// Get the moving average

Movavg = EMA(C,periods);

// set the color using IIF

Linecolor = IIf(movavg> Ref(C,-1),colorGreen,colorRed);

// Now plot the variable

Plot(movavg,"Signal",Linecolor,styleLine);

Hope this helps

Subject: [amibroker] Using IIF statement

I'm trying to change the color of a moving average, depending upon if
it is upsloping or downsloping. I have tried to imbed the IIF
statement in the 'Plot' command where the color arguement goes (to no
avail), and am presently trying to imbed the 'Plot' statement in the
IIF command. Both are getting error 30 or 31 ...... here is the 2nd
attempt.

IIf(EMA>Ref(-1),Plot( EMA( P, Periods ), _DEFAULT_NAME(),colorRed,
style=styleLine
),Plot(EMA(P,Periods),_DEFAULT_NAME(),colorBlue,style=styleLine));

Any help on what's wrong with this logic would be appreciated.
Thanks
