Elementary math.
MACD fluctuates between positive and negative values, often crossing
through zero. You code contains DIVISION by MACD, thus
division BY ZERO.
ANY number divided by zero results in +/- INFINITY.

Subject: [amibroker] Re: roc of macd
excusme, TJ,buy i've tried previosly also whith same efect's.
also hidden macd plot and only displaying roc (original or
calculated) allways have similar results.it don't be a (more or
less) "smooth" plot at all.
i've just retried with
k=Ref (MACD(5,13),-3);
j=MACD (5,13);
r= (k-j)/k;
code lines and is the same
can you put a graph of that¿?
thanks
