It seems that the formula below for predicting the closing price
needed for the signal line to cross the MACD is not as accurate as
it could be. The reason, at least with my version of MS (7.03), is
that the MACD in MetaStock is based on EMA's that are slightly off
the assumed 12/26 periods. The MACD EMA's are calculated using
proportions of 0.075 and 0.15 instead of 2/13 and 2/27. The latter
is what the code you posted uses for the 'top' variable, hence the
small errors that occur when tested against the MS canned MACD.
I've taken the liberty of revamping the code so that the predictive
prices work for my version of MS.

{MACD MS Look Ahead}
x:=0.15; y:=0.075;
a:=If(Cum(1)=1,C,PREV*(1-x)+C*x);
b:=If(Cum(1)=1,C,PREV*(1-y)+C*y);
a:=a*(1-x); b:=b*(1-y); top:=b-a;
{C required for signal/MACD crossover}
(Mov(MACD(),9,E)+top)/(x-y);
