Its a tightening of the MACD crossover using metastock software...to avoid time lag triggers as much as possible.....with all these tweaks more false signals can be triggered especially during non trending times......best to combine with trend ocillators like RSI's


The standard MACD configuration is:
The Moving Average Convergence/Divergence indicator (MACD) is calculated by subtracting the value of a 0.075 (26-period) exponential moving average from a 0.15 (12-period) exponential moving average. A 9-period dotted exponential moving average (the "signal line") is automatically displayed on top of the MACD indicator line.

The Zero Lag is a bit more complex
without confounding yoo to much the formula is
EMA1:= Mov(CLOSE,13,E);
EMA2:= Mov(EMA1,13,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA13:= EMA1 + Difference;
EMA1:= Mov(CLOSE,21,E);
EMA2:= Mov(EMA1,21,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA21:= EMA1 + Difference;
ZeroLagMACD:=ZeroLagEMA13 - ZeroLagEMA21;
ZeroLagMACD

and the trigger is

EMA1:= Mov(CLOSE,13,E);
EMA2:= Mov(EMA1,13,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA13:= EMA1 + Difference;
EMA1:= Mov(CLOSE,21,E);
EMA2:= Mov(EMA1,21,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA21:= EMA1 + Difference;
ZeroLagMACD:=ZeroLagEMA13 - ZeroLagEMA21;
EMA1:= Mov(ZeroLagMACD,8,E);
EMA2:= Mov(EMA1,8,E);
Difference:= EMA1 - EMA2;
ZeroLagTRIG:= EMA1 + Difference;
ZeroLagTRIG


so its a 21/13 subtraction and 8 period trigger subtraction for starters vs a 26/12 and 9period trigger


heres what they look like......cheers
