Signal size (font )

#1

Hello everyone, how can we change signal size to be larger.
usually they come with a fixed size.

how to change FONT in the two particular formulas ??

< shape=IIf(g,shapeDownTriangle*(x==t1),shapeUpTriangle*(x ==t11));
Color=IIf(g,colorRed,colorGreen); >

<PlotShapes( IIf( Buy, shapeSmallUpTriangle, shapeNone ), colorWhite, layer = 0,yposition = HaLow, offset = -30);
//PlotShapes( IIf( Buy, shapeSmallCircle, shapeNone ), colorWhite, layer = 0,yposition = HaLow, offset = -8); >

Thanks in advance

I'm not a chart expert but I see a couple of possibilities.

First almost anything you want to see on the screen can be done with low level graphics capabilities,

But also consider that since AmiBroker version 5.80, PlotTextSetFont can use the windings.

For example,

SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
Plot( C, "Close", ParamColor("Color", colorDefault ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() ); 

buy1 = Cross(MACD(), Signal());


Size1 = param("FontSize1", 40, 30, 90, 5);

// draw an up arrow
for ( i = 2; i < BarCount; i++ )
{
    if ( buy1[i] )
        PlotTextSetFont( "#", "Wingdings 3", size1, i - 1, L[i], colorGreen, colorDefault, -(size1+20) );
   
}

I think this can serve as a reference (but not certain)
