Maybe you could try this:
r1=5;r2=8;r3=9;
ml = MACD(r1, r2);
//sl = Signal(r1,r2,r3);
Plot( ml , StrFormat(_SECTION_NAME()+"(%g,%g)", r1, r2), colorRed,
ParamStyle("MACD style") );
//Plot( sl , "Signal" + _PARAM_VALUES(), ParamColor("Signal color",
colorBlue ), ParamStyle("Signal style") );
O=H=L=C=ml;
acc = Param("Acceleration", 0.1, 0, 1, 0.001 );
accm = Param("Max. acceleration", 0.11, 0, 1, 0.001 );
Plot( SAR( acc, accm ), _DEFAULT_NAME(), ParamColor( "Color",
colorCycle ), ParamStyle("Style", styleDots | styleNoLine, maskDefault
| styleDots | styleNoLine ) );
