[binjobingo]

I am   trying to wite a macd with Hull but the Macd is comong
something different

Hull MA (9) -  Hull MA (18)

I tried the afl this way please point out the mistake

_SECTION_BEGIN("MACD WITH HULL");
MAV1=P = ParamField( "Price field", -1 );
Period = Param( "Period", 9, 1, 100, 1 );
Hull = WMA( 2 * WMA( P, int( Period / 2 ) ) - WMA( P, Period ), int(
sqrt( Period ) ) );




MAV2=P = ParamField( "Price field", -1 );
Period = Param( "Period", 18, 1, 100, 1 );
Hull = WMA( 2 * WMA( P, int( Period / 2 ) ) - WMA( P, Period ), int(
sqrt( Period ) ) );



r1 = Param( "MAV1", 9, 2, 200, 1 );
r2 = Param( "mav2", 18, 2, 200, 1 );


Plot( ml = MACD(r1, r2), StrFormat(_SECTION_NAME()+"(%g,%g)", r1, r2),
ParamColor("MACD color", colorRed ), ParamStyle("MACD style") );
