Screener Divergence MACD

Please find below the MACD divergence indicator converted to screener code: 

// DIVERGENCES ZeroLag MACD adapted from HK-LISSE RSI divergences code

//MACD periods
short = 12
long = 26
signal = 9
//-----------

EMAshort1 = exponentialaverage[short](close)
EMAshort2 = exponentialaverage[short](EMAshort1)
DifferenceShort = EMAshort1 - EMAshort2
ZeroLagShort = EMAshort1 + DifferenceShort

EMAlong1 = exponentialaverage[long](close)
EMAlong2 = exponentialaverage[long](EMAlong1)
DifferenceLong = EMAlong1 - EMAlong2
ZeroLagLong = EMAlong1 + DifferenceLong

ZeroLagMACD = ZeroLagShort - ZeroLagLong

signal1=ExponentialAverage[signal](ZEROLAGMACD)
signal2=ExponentialAverage[signal](signal1)
DIFFERENCE2=signal1-signal2

SignalMACD=signal1+DIFFERENCE2
x = ZeroLagMACD
y = SignalMACD
