[amibroker] Re: roc of macd

["trikerito" <trikero@xxxxxxxxxxx>]

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
