It still does not work. 

These are the settings :
fast= .108, slow = .213, average = .199

Formula:

EMA1current = EMA1previous + SF1 ( Close - EMA1previous )
EMA2current = EMA2previous + SF2 ( Close - EMA2previous )
MACDcurrent = EMA1current - EMA2current
Signal Line = MACD previous + SLSF ( MACDcurrent - MACDprevious )

SF=2/(N+1)


//Dinapoli MACD
FastLength = Param("FastLength",8,0,36,2);
SlowLength = Param("SlowLength",17,0,52,2);
MACMA = Param("MACMA",9,0,15,1);


SmoothingFactor1 = 2 / ( fastlength + 1 ) ;
SmoothingFactor2 = 2 / ( slowlength + 1 ) ;
SmoothingFactor3 = 2 / ( MACMA + 1 ) ;

EMA1 = AMA (Close,fastlength) ;
EMAfast = EMA1 + ( SmoothingFactor1 * (Close-EMA1) ) ;

EMA2 = AMA (Close,slowlength) ;
EMAslow = EMA2 + ( SmoothingFactor2 * (Close - EMA2) ) ;

MACD1 = EMAfast-EMAslow ;


Plot( MACD1, StrFormat(_SECTION_NAME()+"(%g,%g)", fastlength,slowlength), ParamColor("MACD color", colorRed ), ParamStyle("MACD style") );

EMA requires bars (or days) as integers. You are using a formula that converts number of bars (as integers) into a fractional smoothing factor. This smoothing factor works with AMA and should be between 0 and 1.00. Change your two EMA() to AMA() and your Param statements must use integers if you're going to use smoothing. The param statement should be something like this:

 

FastLength = Param("FastLength",8,2,200,1);

There is something wrong with this formula and I can't figure it out.

FastLength = Param("FastLength",.213,0,36,2);
SlowLength = Param("SlowLength",.108,0,52,2);
MACMA = Param("MACMA",.199,0,15,1);


SmoothingFactor1 = 2 / ( fastlength + 1 ) ;
SmoothingFactor2 = 2 / ( slowlength + 1 ) ;
SmoothingFactor3 = 2 / ( MACMA + 1 ) ;

EMA1 = EMA (Close, fastlength) ;
EMAfast = EMA1 + ( SmoothingFactor1 * (Close-EMA1) ) ;

EMA2 = EMA (Close, slowlength );
EMAslow = EMA2 + ( SmoothingFactor2 * (Close - EMA2) ) ;

MACD1 = EMAfast-EMAslow ;


Plot (MACD1, "", 5, 4 ) ;
