Re: [amibroker] ref(x, 1)

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

It returns last value. In other words, you can't look into "future" values.

It is however possible to PLOT into the future "blank" space,
by means of XShift parameter.

DispMA shipped with AmiBroker shows how:

P = ParamField("Field"); 
Type = ParamList("Type", "Simple,Exponential,Double Exponential,Tripple Exponential,Wilders,Weighted"); 
Periods = Param("Periods", 30, 2, 300 ); 
Displacement = Param("Displacement", 15, -50, 50 ); 
m = 0; 

if( Type == "Simple" )                m = MA( P, Periods ); 
if( Type == "Exponential" )          m = EMA( P, Periods ); 
if( Type == "Double Exponential" )    m = DEMA( P, Periods ); 
if( Type == "Tripple Exponential" )    m = TEMA( P, Periods ); 
if( Type == "Wilders" )             m = Wilders( P, Periods ); 
if( Type == "Weighted" )             m = WMA( P, Periods ); 

Plot( m, _DEFAULT_NAME(), ParamColor("Color", ColorCycle), ParamStyle("Style"), 0, 0, Displacement );
