For EMA copy paste below given code in afl writing. Analysis>Formula Editor and paste and insert, better save at some place before inserting and try 3000 day ema if you have data though :).

KelvinHand already told you what to do and what to change!

http://www.amibroker.com/guide/afl/param.html

Code: 
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 9000, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
Click reset all button in parameter dialog after you have edited an already applied indicator's param code.
