Re: [amibroker] Plotting Sine Waves using Time Axis

["Steve Dugas" <sjdugas@xxxxxxxxxxx>]

Hi - Here is a pretty flexible tool for plotting cycles / sine waves, hope 
it helps

// Cycles

// set chart options

SetBarsRequired( 10000, 10000 );

SetChartOptions( 0, chartShowDates );

Periods = Param( "Cycle Pds", 13, 1, 252, 1 );

XShift = Param( "Shift L/R", 0, -252, 252, 1 ) / 3.14159^2;

XFactor = Param( "FT Freq", 1, 0, 2, 0.001 );

YFactor = Param( "FT Amp", 1, 0, 1, 0.01 );

Color = ParamColor( "Color", colorYellow );

// calc and plot wave

X = 2 * 3.14159 / Periods / XFactor;

Y = sin( Cum( X ) - XShift ) * YFactor;

FineTunedPds = Periods * XFactor;

Plot( Y, NumToStr( FineTunedPds, 0.2 ) + " Bar Cycle", Color, 
styleLine|styleLeftAxisScale|styleNoLabel );

Plot( 0, "", Color, styleLine|styleDashed|styleLeftAxisScale|styleNoLabel );

Plot( 1, "", Color, styleNoLine|styleLeftAxisScale|styleNoLabel );

Plot( -1, "", Color, styleNoLine|styleLeftAxisScale|styleNoLabel );

// calc and plot vertical lines for pivots

Ym1 = Ref( Y, -1 );

Yp1 = Ref( Y, 1 );

Peaks = Y > Ym1 AND Y > Yp1;

Troughs = Y < Ym1 AND Y < Yp1;

Pivots = IIf( Peaks, YFactor, IIf( Troughs, -YFactor, Null ) );

Plot( Pivots, "", Color, 
styleHistogram|styleDashed|styleLeftAxisScale|styleNoLabel );

Plot( -Pivots, "", Color, 
styleHistogram|styleDashed|styleLeftAxisScale|styleNoLabel );
